Yes, I was being an idiot ! I didn't realise what the netmask was ... I've now adjusted what I'm doing in light of what people have been saying (here and in the IRC channel on freenode) such that my config is now: xmclient:~# ifconfig eth0 10.0.1.1 netmask 255.255.255.0 xmclient:~# route add -net 10.0.4.0 netmask 255.255.255.0 gw 10.0.1.254 xmrouter1:~# ifconfig eth0 10.0.1.254 netmask 255.255.255.0 xmrouter1:~# ifconfig eth1 10.0.2.1 netmask 255.255.255.0 xmrouter1:~# route add -net 10.0.4.0 netmask 255.255.255.0 gw 10.0.2.254 xmrouter1:~# echo 1 > /proc/sys/net/ipv4/ip_forward xmrouter2:~# ifconfig eth0 10.0.2.254 netmask 255.255.255.0 xmrouter2:~# ifconfig eth1 10.0.3.1 netmask 255.255.255.0 xmrouter2:~# route add -net 10.0.4.0 netmask 255.255.255.0 gw 10.0.3.254 xmrouter2:~# route add -net 10.0.1.0 netmask 255.255.255.0 gw 10.0.2.1 xmrouter2:~# echo 1 > /proc/sys/net/ipv4/ip_forward xmrouter3:~# ifconfig eth0 10.0.3.254 netmask 255.255.255.0 xmrouter3:~# ifconfig eth1 10.0.4.1 netmask 255.255.255.0 xmrouter3:~# route add -net 10.0.1.0 netmask 255.255.255.0 gw 10.0.3.1 xmrouter3:~# echo 1 > /proc/sys/net/ipv4/ip_forward xmserver:~# ifconfig eth0 10.0.4.254 netmask 255.255.255.0 xmserver:~# route add -net 10.0.1.0 netmask 255.255.255.0 gw 10.0.4.1 xmserver:~# ping 10.0.1.1 PING 10.0.1.1 (10.0.1.1) 56(84) bytes of data. 64 bytes from 10.0.1.1: icmp_seq=1 ttl=61 time=35.1 ms 64 bytes from 10.0.1.1: icmp_seq=2 ttl=61 time=0.824 ms 64 bytes from 10.0.1.1: icmp_seq=3 ttl=61 time=0.889 ms This is good - I know the routers are being used because the ttl is < 64 and if I shut down one of the routers it stops working :-) Huzzah it's solved... xmserver:~# traceroute 10.0.1.1 -d traceroute to 10.0.1.1 (10.0.1.1), 30 hops max, 38 byte packets 1 10.0.4.1 (10.0.4.1) 1.214 ms 0.228 ms 0.082 ms 2 * * * 3 * * * 4 * * 10.0.1.1 (10.0.1.1) 29.752 ms Damn - why are 2 and 3 giving me *'s?
