Thanks... but I think I need a bit more help.
bartok # ./ip route show 129.94.232.0/24 via 129.94.172.66 dev eth1 129.94.242.0/24 dev eth0 proto kernel scope link src 129.94.242.45 129.94.241.0/24 via 129.94.174.2 dev eth1 129.94.172.0/22 dev eth1 proto kernel scope link src 129.94.172.12 129.94.208.0/22 dev eth2 proto kernel scope link src 129.94.208.2 default via 129.94.242.1 dev eth0 bartok # ip addr show 1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo 2: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 100 link/ether 00:10:4b:1c:a3:a4 brd ff:ff:ff:ff:ff:ff inet 129.94.242.45/24 brd 129.94.242.255 scope global eth0 3: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 100 link/ether 00:a0:c9:8f:7f:3c brd ff:ff:ff:ff:ff:ff inet 129.94.172.12/22 brd 129.94.242.255 scope global eth1 4: eth2: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 100 link/ether 00:90:27:37:bb:d5 brd ff:ff:ff:ff:ff:ff inet 129.94.208.2/22 brd 129.94.242.255 scope global eth2
The client in question is 129.94.211.194 It sends a UDP request to 129.94.172.12 The reply, addressed to 129.94.211.194 causes ARP requests on bartok's eth1
Surely the route that applies is the 4th one, which seems to have a correct 'src' parameter.
BTW, The routes were all created with 'route', not 'ip', incase it matters.
