Routers路由器

这里是一些路由器介绍以及如何进行允许设置连接到aMule的端口。

在下面的介绍中,示例使用的是默认的端口(就是4662标准客户端TCP端口4672扩展客户端UDP端口以及4665扩展服务器请求UDP端口)。

Linksys WRT54GSV4

  1. 打开您的浏览器,输入地址 http://192.168.1.1然后登录。
  2. 进入Gaming applications
  3. 然后允许连接到您电脑的端口:
    1. [[Standard client TCP port]|标准客户端TCP端口]
      1. 更改起始端口(Ports start)结束端口(End)全部为4662
      2. 在下一项目设置为TCP
      3. 在项目中,最后3个数字是您的局域网 IP
    2. 扩展客户端UDP端口
      1. 更改起始端口(Ports start)结束端口(End)全部为4672
      2. 下一项目设置为UDP
      3. 在项目中,最后3个数字是您的局域网 IP
    3. 扩展服务器请求UDP端口
      1. 更改起始端口(Ports start)结束端口(End)全部为4665
      2. 下一项目设置为UDP
      3. 在项目中,最后3个数字是您的局域网 IP
  4. 然后选中 允许(Enable)'
  5. 然后点击保存设置(Save settings)
  6. 然后重启aMule :)

Linksys Router configuration

This portion of the wiki applies only to stock versions of the Linksys firmware. If you are using a Linksys router running a variant of the GPL code, please follow the guides directly above as you are most likely using iptables.

Log into your Linksys router. After successfully logging in, click on the main menu link labeled Applications & Gaming after which you should see an additional submenu list for this section. Make sure you are under the correct submenu by clicking Port Range Forwarding.

At this point, you should see a table with 6 columns. The columns are: Application, Start to, End, Protocol, IP Address, Enable.

The Application column
Friendly name for the service. Put anything you want here, aMule being suggested.

The Start to -> End column
Start and end ports. Start to should be 4662 but, in the end, this should reflect whatever port you have defined in aMule Preferences -> Connection -> Client TCP Port. End should be 4672 but, in the end, this should reflect whatever port you have defined in aMule Preferences -> Connection -> eMule extended UDP Port.

I suggest using 2 separate entries for each port unless this is not possible.

The Protocol column
Protocol to listen for. If you use one line to open your aMule ports, set this option to Both. If you use a separate entry line for each, select option TCP for Client TCP Port and option UDP for eMule extended UDP Port.

The IP Address column
Internal IP address to forward requests to. This is typically the internal (private) IP address of the computer that will use aMule.

The Enable column
Enable rule. You'll need to check this in order to enable your aMule rules.

After adding your rule, make sure you save your settings. You can verify whether your rules work by testing your ports.

DLink Router configuration

Log in to your DLink router. There are three steps to take to enable your aMule ports.

IP Address setup

In the Home tab, click the DHCP button. This page displays the current IP addresses assigned by the router, both static and dynamic. Look for the name or MAC address of the computer you'll be running aMule on. If your computer is receiving dynamically assigned IP addresses, you will have to change your settings every so often if your IP address changes. To avoid this, use the Static DHCP section, and perform the following steps:

  • Name: Type in the name of your computer here, could be anything
  • IP: The IP address you want the router to always assign to your computer
  • MAC Address: The MAC address of your computer. You should be already connected to the router, so you can find your computer in the DHCP Client drop-down menu, and click clone, to populate this number
  • Click Apply

Now your computer will always receive the same IP address.

Now click on the Advanced tab, and there are two areas that need to be updated:

Virtual Server

  • Click the Virtual Server button. This page forwards external requests to a specific internal IP address in your network
  • Click Enabled
  • Enter a name in the Name entry box, eg aMule TCP
  • Enter your static IP address in the Private IP box
  • Select TCP in Protocol type
  • Private port is the port that the router will forward the requests to on your computer. This can be anything, a good value is the default aMule TCP port, 4662
  • Public port is the port that the router will receive requests on. Again, a good value is the aMule TCP port of 4662
  • Schedule is the times at which the port is open. Select Always, or whatever times you wish
  • Click Apply

Applications

  • Click the Applications button. This page allows you to enter a range of ports to open for application usage
  • Click Enabled
  • Enter the TCP port in the first Trigger Port box, a good value being 4662
  • Select Trigger Type as TCP
  • In Public Port, enter the range from your aMule TCP port to your aMule UDP port, usually 4662-4672
  • Select UDP as the Public Type
  • Click Apply

You should now be all set, assuming that your computer firewall is setup to allow access on the selected ports.

Alternate Configuration (ie instead of Applications) for D-Link

  • Go back to virtual server and set 2 other virtual servers for the UDP ports

(It works only that way on my D-Link DI-804HV)

  • Virtual server aMuleUDP4665 - select your IP address and UDP and 4665 (port)
  • Virtual Server aMuleUDP4672 - select your ip address and UDP and 4672 (port)

(disable the above amule applications if you did try and it do not work). Then you shoudl have all arrows green ( and 3 virtual servers running for amule, 1 for TCP and 2 for UDP).

Another Alternate Configuration (using Firewall rules) for D-Link (tested on D-Link DI-624)

  • Click on Advanced tab then click on Firewall. This page can be used to setup firewall rules directly Without ANY further settings in Virtual server or Applications tabs
  • Click Enabled
  • Enter your preferred name for the rule (must be unique)
  • Select WAN as source interface and * for source IP Range Start (IP Range End can be left blank)
  • Select LAN as destination interface and enter the static IP of your PC running aMule for destination IP Range Start (IP Range End can be left blank)
  • Select * as destination protocol
  • Enter 4662-4672 as destination port range
  • Select your preferred scheduling
  • Click apply

IMPORTANT NOTE: disable all existing entries for aMule you may have specified in Virtual server or Applications tabs.

  • Reboot your router to be sure new configuration is applied (Tools -> Misc).


Belkin Router configuration

Log in to your Belkin router: 192.168.2.1. You will be following these steps twice: once to create a TCP record, and again to create a UDP record.

  • Click the Virtual Servers link in the Firewall section on the left. This page forwards external requests to a specific internal IP address in your network
  • Pick the first empty row
  • Check Enabled
  • Enter any name you like in the Description entry box, eg: aMule TCP/UDP
  • For the Inbound port entry boxes, enter 4660 and 4712.
  • Select TCP or UDP out of the Type dropdown. If you already have one set up, pick the other.
  • For Private IP address enter the IP address the router assigned your machine. There are many ways to find this. Ubuntu users might want to use gnome-nettool (Network Tools) and look at the IPv4 entry under the appropriate network interface. If you like the terminal, type ifconfig and look for the inet addr entry. If you're in Windows, you can type ipconfig from the command line. No matter how you do it, the number should look like 192.168.2.x where x is the number you will be entering.
  • Private port is the port that the router will forward the requests to on your computer. Though this can be anything, the default aMule port is 4662 for TCP and 4672 for UDP. Entering 4660 and 4712, same as the inbound port range above, will cover other possible ports.
  • Repeat the steps above to make sure you have an entry for both TCP and another entry for UDP.
  • Click Apply
  • If you have aMule open, go to it click Disconnect. When the button changes, click Connect. Kad should no longer be firewalled and you should not get another Low ID error. If you do still have issues, make sure you completed all the steps correctly by testing your ports: http://www.amule.org/testport.php

Keep in mind that the Private IP address number could change if you're ever disconnected from the router, because it is dynamically assigned by default.

Netgear router

First, go to your router control page, locate at http://routerlogin.net/start.htm. Then, on the left side of the screen, under the Advanced group of options, click "Port Forwarding/Port Triggering." Click the "Add Custom Service" button, name it aMule1 (or whatever), set it as a TCP-only forwarding, with the starting and ending port being 4662 and the server IP address being whatever local address you're using (probably 192.168.1.2, if you're the only one connected to the router, but check), and click Apply. Repeat the process with aMule2 and aMule 3, using UDP-only ports for both and starting and ending ports of 4665 and 4672, respectively. (That is, the same starting and ending port within aMule2 and aMule3, but aMule2=4665 and aMule3=4672.) Make sure that iptables is properly set up on the machine which will run aMule (as above), and you're done.

Not all Netgear routers are the same, evidently, because on the DG834G it's more complicated. Go to the router's configuration page:

  1. Select Services from the Content Filtering menu
  2. Add your three rules (1 x TCP, 2 x UDP) based on your aMule Connection preferences
  3. Select Firewall Rules from the same menu
  4. Add all three rules as Inbound Services
  5. Add both UDP rules as Outbound Services (only one of these is crucial but I add the other just in case)

TRENDnet router TW100

First connect to your router: usually open a browser and type directly the router IP address: such as 192.168.0.1 (or 192.168.1.1), then the login box should appear ( depending on your router config) - if so answer the message log message with ‘admin’ as username and nothing as password (or you password if you did set one). 首次连接到您的路由器:通常打开浏览器然后直接输入路由器IP地址:例如 192.168.0.1 (or 192.168.1.1),然后登录框会出现(具体依赖于在您的路由器配置)-如果这样,输入用户名'admin',密码为空(或者是您设定好的那个)。

然后在左侧菜单,选择网络(Internet)然后选择高级设置(高级网络,Advanced Internet),然后点击/选择,[Special Applications|特殊应用程序(Special Applications)]:

在特殊应用程序(Special Applications)列表中添加或者替换成两行内容: (请不要删除您在使用和已经被可用的内容) (例如仅仅在Nr.5或者Nr.6后面添加新的amule应用程序)

创建如下全部内容:

amuleU4665 TCP-4665-4665 UDP-4665-4665

amuleU4672 TCP-4672-4672 UDP-4672-4672 )

(在我的应用列表中 “amuleU4665” 和 “amule4672”处于Nr1和Nr2,但可以在您列表中的任何位置)。

->点击左侧的小框[ ]中的类似amuleUxxxx的应用程序来使特殊应用程序可以工作。

然后点击[保存],接着点击[关闭]

接着在页面-高级网络(Advanced Internet)点击[保存]

最后的步骤就是点击左侧的“虚拟服务器(Virtual Servers)”菜单,“虚拟服务器页面会出现“

添加一个新的虚拟服务器,名称为:AmuleTCP

选择您电脑*IP地址:在下拉菜单中选择

选择:TCP

输入4662端口和4662端口(两个输入为同一端口)

然后[添加为新服务器(Add as new server)]

Then you are set to have High ID and Kad ON. Finished with the Low-ID, yellow arrows and Kad Firewalled. Now all you arrows should be green and you should have access to Kad and ed2K. 接着就会设置为拥有 高ID(HighID)和Kad网络允许(ON)。

特别注意:

  • 在您的电脑使用DHCP时Be careful in the case that your computer is using the DHCP protocol (ie to obtain IP address from the router).

The router might not give all the time the same IP address to your computer. (normally it does so... but sometimes it can change). You have two solutions if you see that you have a low- ID then: (2 solutions)

1) log back to the router go back to the virtual server, select the amuleTCP virtual server that you created and just reselect you computer in the “PC(server)” entry box. And select [Update this server] and log out. It should do the job.

Or an alternative solution :

2)You can Set-up your computer with a fixed IP address if you want. If this problem of low-ID happens too often because you DHCP router gives different IP address to your computer, then you can put your computer in static mode or DHCP reserved address. But you need to know your DNS server(s) before to do that – so check with your ISP which are your DNS servers. Then configure your computer to run with a fixed DHCP/ Static address / Manual Address (name depends what OS you are running). For that go to your network settings and put the P address you want, and the gateway (you router IP address) and the DNS from your ISP – All this to be done ion the Other / PC Database (Admin) page of the router.

In the case that your TRENDNet router crashes or stop forwarding any traffic from/to your aMule computer . (it happened to me), then :

- reduce the Connection limit (in Preferences->Connection) to 100 (or to 50) - reduce the "Max new connections / 5 secs" (in Preferences->Core Tweaks) to 10 (or to 5) Stop amule and restart aMule so that configuration will be validated.

Make some tests to find your best config. It should give more stability to your router and avoid your router to crash ( ie you would have to reset and/or turn it on and off). This might be true for other routers as well(?).

OpenBSD

The firewall that comes with OpenBSD is called packetfilter (pf). To get aMule running, you must add the following rules to your pf.conf ( OpenBSD上的防火墙叫做 packetfilter (pf),为了是aMule运行,您必须将下面规则添加到您的pf.conf文件(/etc/pf.conf):

 # aMule TCP 和 UDP
 rdr pass on egress proto tcp to port 4662 -> IPADDR
 rdr pass on egress proto udp to port 4672 -> IPADDR
 rdr pass on egress proto udp to port 4665 -> IPADDR

IPADDR is the internal ip-address of the computer in your network that runs aMule. IPADDR是在网络上运行aMule电脑的内网IP地址。 Pf guesses automatically the name of the outter interface (connected with the internet), thanks to the keyword "egress" ( this means: "the interface where goes the default route", and it's updated dynamicaly in case of change).
多亏关键字egress,Pf能够自动猜测外部网络接口名称(连接互联网的),(这意味着,网络接口网络接口如果有更改它将动态更新)。

示例(运行aMule的电脑IP是192.168.1.10):

 # aMule TCP 和 UDP
 rdr pass on egress proto tcp to port 4662 -> 192.168.1.10
 rdr pass on egress proto udp to port 4672 -> 192.168.1.10
 rdr pass on egress proto udp to port 4665 -> 192.168.1.10

当然,为了使运行aMule的电脑必须有权限连接网络,所以也要添加下面规则:

 nat on egress from IPADDR to any -> (egress)

IPADDR是在网络上运行aMule电脑的内网IP地址。

示例(像上面):

 nat on egress from 192.168.1.10 to any -> (egress)

为了激活更改后的配置,重启或者执行下面命令:

 pfctl -f /etc/pf.conf

为了在启动时自动加载防火墙:

 echo PF=yes >> /etc/rc.conf.local


为了使KAD顺利连接而不是被防火墙阻拦,将下面内容放在pf.conf文件NAT字段的前面(因为NAT规则使用列表的第一个匹配,而不像pf.conf的其他部分):

 no nat on egress proto udp from 192.168.1.10 port 4672 to any
