The main machine also has a isdn dialup connection. Networking works well except if I let the main machine masquerade so the other can use the internet too. I use iptables for this. It works for a day or so, then eth0 goes silent on the main machine. (Rebooting it shows that the other one was fine all the time.) The symptoms is that there is no contact between the two machines. No ping or anything. "ifconfig" shows the interface is up with the correct ip address, but all packets just disappear. There are no error messages except from programs that time out. Bringing the interface down and up again with ifconfig does not help. It is compiled into the kernel, so I can't try module reloading. Is this some sort of known problem? Or is there something I could do to find out more? I couldn't find anything in the logfiles. Helge Hafting.
