I am afraid I am floundering with what should be a simple problem. I have a 9.1 box that operates as a firewall/router for a home network. Some of the workstaions are Windows XP. One of the windows XP staions wants to use emule. I have tried with and without masquerading, a midified /sbin/Susefirewall2 script, and an add on custom script. I have , in fact, gotten myself thorughly confused and tangled. Does anyone have an /etc/sysconfig/Susefirewall2 parameter script that works with emule that they would share? Many thanks, John Lederer ============================ Emule firewall requirments 1) /Local Port:/ 4662 /Remote Port:/ any /Protocol:/ TCP /Direction:/ incoming /Purpose:/ Client Port / Connections from other clients, Client to Client Source Exchange /Note:/ You can change this port in /Preferences -> Connection ->/ /Client Port/ This port has to be forwarded in a router. Changing this port in Preferences you must also change the forwarding in the router 2) /Local Port:/ any /Remote Port:/ 4662 /Protocol:/ TCP /Direction:/ outgoing /Purpose:/ Client Port / Connections to other clients, Client to Client Source Exchange /Note:/ 4662 is the default port, but other clients may have different settings. Change the /remote port/ to /any/ when configuring a firewall 3) /Local Port:/ 4672 /Remote Port:/ any /Protocol:/ UDP /Direction:/ incoming /Purpose:/ Clients source asking / extended eMule protocol, Queue Rating, File Reask Ping /Note:/ This port has to be forwarded in a router. Changing this port in Preferences you must also change the forwarding in the router. If you are not able to forward this port check the /disable/ box in /Preferences -> Connection -> UDP Port/ 4) /Local Port:/ any /Remote Port:/ 4672 /Protocol:/ UDP /Direction:/ outgoing /Purpose:/ Clients source asking / extended eMule protocol, Queue Rating, File Reask Ping /Note:/ 4672 is the default port, but other clients may have different settings. Change the /remote port/ to /any/ when configuring a firewall 5) /Local Port:/ any /Remote Port:/ 4661 /Protocol:/ TCP /Direction:/ outgoing /Purpose:/ Connection to server /Note:/ 4661 is the default port of a server. Many server use different ports. Configuring a firewall the /remote port/ again changes to /any/. 6) /Local Port:/ any /Remote Port:/ 4665 /Protocol:/ UDP /Direction:/ outgoing /Purpose:/ Source asking on servers /Note:/ Servers using the default port 4661 TCP (see #5) automatically set their port for source asking to 4665 UDP. If a server uses a different port in #5 the corresponding UDP port is set to [Connection Port + 4]. For firewalls the /remote port /here is /any./ 7) /Local Port:/ 4711 /Remote Port:/ any /Protocol:/ TCP /Direction:/ incoming /Purpose:/ Webserver /Note:/ This is the default port for the web interface. When using a router this port has to be forwarded or no connection to the webserver will be possible.
