Re: Can't get LAN to work
Hi tunk,
thanks for the help. I think I will do the same.
I tried to get it work with NetworkManager and I believe I know now why it is not working; NetworkManager does not look in /etc/sysconfig/network-scripts for the ppp0 config but in /etc/NetworkManager.

iptables firewall
Not sure I am asking too much now... Attached is the script of the firewall I am using on my home server which is modem/router and serves the LAN. Wanted to get an expert opinion whether this is good enough of a firewall. #!/bin/sh # ############################################################### ##...
