i setted up my system with Ip-Masquerading and a ISDN dialup to my host.
the only problem is that when the route is added via:
"route add default ippp0"
in my script i have to do it after i made the connection to my server once again, because i only have a dynamic IP address from my ISP so i have to use 0.0.0.0 in my script.
But this way i can´t get the dial on demand on work without first establishing the connection through the Linux Box.
I really hope one of you guys can help me!
