Hi all, I have a problem when i connect on my isdn ippp0 and ifup my eth0. The connection breaks and all i get in the logs is: May 21 19:07:53 marko kernel: martian source 155.239.84.218 from 155.239.88.113, on dev ippp0 May 21 19:07:53 marko kernel: ll header: 45:00:00:30:b3:6c:40:00:7b:06:67:31:9b:ef:58:71:9b:ef May 21 19:07:56 marko kernel: martian source 155.239.84.218 from 155.239.88.113, on dev ippp0 May 21 19:07:56 marko kernel: ll header: 45:00:00:30:b4:20:40:00:7b:06:66:7d:9b:ef:58:71:9b:ef May 21 19:08:30 marko kernel: martian source 155.239.84.218 from 213.95.27.115, on dev ippp0 May 21 19:08:30 marko kernel: ll header: 45:40:05:dc:ea:53:40:00:31:06:77:ec:d5:5f:1b:73:9b:ef May 21 19:08:36 marko kernel: martian source 155.239.84.218 from 155.239.136.234, on dev ippp0 As soon as i bring my eth0 down everything works again. Messages stop and the connection becomes active. Please help me out someone cause im really getting frustrated with it now. It's got nothing to do with the other pc on the network cause when i shutdown it down it same crap happens. P.S. Is there another log where i can get some more info about the connection? I've been trying to get my linux router to connect with "isdnctrl dial ippp0" and all i get is "connected to 011xxxxxxx' and then in 6-7 seconds it dosconnects again. Now im suspecting this isdn modem is faulty but where can i check if it connected at all or it was just trying to dial before i go and buy a new modem. Thanx a lot! Marko
