For firewall relative question there's another, more specific, mail list: debian-firewall@lists.debian.org Anyway, if you are using ppp to connect to your ISP, the ppp0 interface should have a public IP address not a private one like 192.168.0.10. In order to enable kernel ipv4 fowarding you must change: echo 1 > /proc/sys/net/ipv4/ip_forward echo 1 > /proc/sys/net/ipv4/conf/all/forwarding Then you should use NAT with iptables to share your internet connection with a LAN.
