Networking problems with Debian
 

Hi,
I'm sharing my internet connection with Debian. It has two network cards, one goes to internet and second goes to lan. I'm using shorewall and pppoe.
Now I'm having starnge problem, my network works well a while, but after some surfing it suddenly stops working. I can't ping anywhere and when trying to go to some internet page it says connection refused. What might be wrong? This configuration has worked well until now.

Let's see... you can't even ping inside your lan?
If it worked for some time, are you sure it's not a ISP problem? I found out that my ISP frequently changes DNS. Can you ping a numeric IP?

PS: I can't open your rules: page not found

I can ping inside my land, and usually connection stops after I've been using xMule-program some time, it's P2P program. Anyway.. after the connection stops, I can't ping to internet, but after I restart connection by writing "poff" and "pon"-commands it works again. My ISP shouldn't have anything that prevents P2P programs.

btw does pppoe try to make new connection when it has disconnected?

PS. It's not about firewall, I tried testing without firewall and I had same problem.

This is what i have in /var/log/ppp-connect-errors

well if you know how long the connection works b4 it disconnects...you can always write a script with the commands u specified above to restart the connection...i know this will be irritating but you could always use this as the last resort...:)

But what about that buffer space? Can I make the buffer bigger?
