Follow these simple steps to configure your Cisco 677 or 678 Router for eMule. This setup assumes you have a PPPOE connection like DSL running and a static IP.

Start a telnet session with your routers IP. To do so

a) Use the Windows Hyper Terminal and type in a Name (does not matter which) for the new session, choose TCP/IP (Winsock) as connection type then enter your router's LAN IP (normally 10.0.0.1 or 192.168.0.1, but may differ) as the host address

or

b) Go to Start -> Run -> telnet router's LAN IP (normally 10.0.0.1 or 192.168.0.1, but may differ)

In the telnet sessions that starts enter these commands each on a single line:

your_password (Provided by your ISP, in rare cases cisco if not changed)
enable
your_password (Provided by your ISP, in rare cases cisco if not changed)
set nat entry add LAN IP  4662 WAN IP 4662 tcp
set nat entry add LAN IP  4672 WAN IP 4672 udp
write
reboot

WAN IP is the IP address you have on the internet (Router's external IP) and LAN IP is the IP address of your computer running eMule.

Note:
If anyone knows how to setup this router for dynamically assigned IPs, please mail Monk
