Hi again!
I've now got my internet sharing sorted, the main problem after a few tweaks with the /etc and /etc/sysconfig network type files was I hadn't set the firewall to recieve DNS requests to the LAN
Anyway, my question now is do I have to go to my machine that has the internet connection and manually start KPPP to dial up to my ISP or can it be done on a client machine when I start Mozilla on it? Its a 56k dial up unfortuanately.
