use ip route so presume server A eth0 192.168.11.10/24 normal traffic eth1 192.168.11.11/24 nfs traffic nfs eth0 192.168.11.14/24 so on server a you could have something like 192.168.11.0 dev eth0 src 192.168.11.10 192.168.11.0 dev eth1 src 192.168.11.11 default via eth0 src 192.168.11.10 you could add ip route add 192.168.11.14/32 dev eth1 src 192.168.11.11 which says for all access to 192.168.11.14 use dev eth1 with src 192.168.11.11 so that will help with outbound traffic - inbound (from nfs to server a) is a different matter. You will find eth0 will arp reply for 192.168.11.11 which means nfs replies will go to eth0 as well as maybe eth1. you could setup a permenant arp entry for 192.168.11.11 on 192.168.11.14 but ..... The other option is put the nfs server in a different subnet (not a different ethernet broadcast segment) - so same switch different ip network, this would stop eth0 being used over eth1 Alex > > Thanks for any info > > . > > > -- > To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject > of "unsubscribe".
