LAN works, PPP doesn't (route.conf?!)

[ZacMacCrac]

Hi,
I'm on a dial-up ISDN connection with dynamic IP address and also have a LAN. I'm using SUSE 6.4.
I've configured the LAN with IPs 192.168.0.x, thats necessary. The dial up internet connection is using dynamic IPs, so I need 192.168.0.99 as dummy for PPP and 192.168.0.1 as point to point partner for PPP (for dyn. IP assignment).
Problem is, I'm already using 192.168.0.x for LAN, so I wonder if that's allowed, I don't think so.
Well, now I deactivated the LAN conn, dialed in just for testing, everything fine until it comes to exchanging packets, I can't surf the internet, I can't ping anyone in the net. (Yes, nameserver's IP is correct.)
Someone told me it would be the routing table that caused the problems. I have no idea how to configure the route.conf properly, nor do I know how to fix the LAN<->PPP<->IP problem. I'm completely lost, please help me.... ;'(

I have a similar setup, though, I'm not trying to share the connection yet...

I have a ppp connection w/a regular modem and also a lan w/my wifes computer....

the PPP connection has a different netmask than my lan connection...
The 192.168.0.x is a class C network (netmask 255.255.255.0), whereas my dialup connection is a class A (i think) (netmask 255.255.255.255)....

ifconfig will tell you the netmasks and such...

I am curious why you are trying to set up the internet connection on your internal network... You can use ipmasking to share the connection...

I'm not setting up the isp connection on the LAN... I'll be using squid to set my machine up as a proxy. But I just NEED the LAN's IPs to be 192.168.0.x, cause the LAN is a bit bigger...
so if I use 255.255.255.0 as netmask for the LAN, and 255.255.255.255 for the dial up (you always use that one for internet, don't you?!), will I then be able to use 192.168.0.x on both networks without getting into trouble?
