Siemens 4100 dsl modem emule ports

[avnik]

I recently got dsl connection and i am having trouble opening the emule ports. ie 4662 and 4672. There are no routers attached to it. I have had cable connection before and i use to forward the ports through the router. But if through dsl modem being directly connected to my system, i should face lowid problem in emule. Can anyone come out with a solution?

I have a a siemens 4100 dsl modem

Maybe your ISP blocks those ports, I have heard some barbaric ones do.
Can these ports be changed? It's perfectly possible to do so in bittorrent...

Have you tried gibson research's port tester? Go HERE and find the ShieldsUP link, then follow the instructions and enter the port(s) you need to test and see what it tells you.
