Hello Alex, SuSE, Thank you for the in-depth response. Unfortunately I tried (what I could) of this, without success. I'm using 6.0 with the 2.0.36 kernel. Really, what I need is someone with virtually the same setup as me, i.e. a linux machine with ipfwadm set-up to allow other machines to access the Internet, and 2+ other Linux machines on the same network which use the first linux machine as a gateway. If someone has this setup, could they please send me their route.conf file? As per your suggestion for adding -n to the 'route' command, here is the output: Itchy (the gateway/firewall machine): root@itchy:/home/lee > route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.1 0.0.0.0 255.255.255.255 UH 0 0 0 dummy0 158.152.1.222 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 559 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 408 lo 0.0.0.0 158.152.1.222 0.0.0.0 UG 0 0 186 ppp0 and from Scratchy (the machine that doesn't seem to connect to the network) cratchy:~ # route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.4 0.0.0.0 255.255.255.255 UH 0 0 0 dummy0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 1 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 1 lo 0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0 As I say, if anyone has a working setup similar to this, please please email me your /etc/route.conf Best wishes, Lee
