UDP

aMule on our server (what ports to open?)

I installed the aMule RPMs from from Packman. Then I needed to start up aMule once in GUI mode to set up the remote control web interface (enable all remote access and disable unix sockets and give passwords). Thereafter you can just start the aMule daemon via the command line amuled. Sometimes amuleweb fails to load when you start amuld, in such a case you should execute amuleweb separately. After this you can connect to aMule's own web server. I opened TCP port 4662 and UDP ports 4672 and 4665 and on our router I forwarded port 4662 to the machine running aMule.
