-----Original Message----- From: Martin A. Brown <snip> Let me note a few things. First, you need only send a mail to the list, not the individual subscribers. </snip> Eager beaver. My apologies if I transgressed. <snip> This means that you are assigning the same IP to two different ethernet interfaces on the same media segment. That's not strictly forbidden, but unless you take some other steps, the machines on the ethernet will get one MAC address for 10.0.1.4 one some ARP requests, and the other MAC address for other requests. That's not quite deterministic, so your networking will break. </snip> True. This is my intent. My LAN will get the MAC address of eth1 for 10.0.1.4 while my router will get the MAC address of eth1 for the same IP. This is how it is physically arranged. <snip> If you are intending to break the network into two pieces, you have not done so here. You should make routes for the IPs which are reachable on each ethernet. For example: # ip route del 10.0.1.0/24 dev eth1 # ip route add 10.0.1.1 dev eth0 # ip route add default via 10.0.1.1 : #ip ro del 10.0.1.0/24 via 10.0.1.4 dev eth0 : RTNETLINK answers: No such process That's because there is no such route....hence the answer is "RTNETLINK answers: No such process" I'd suggest re-reading the iproute2 command reference to understand the use of the keyword "via". You are not using the right keyword, or not understanding what you are asking of the kernel, here. : #ip ro add 10.0.1.1/24 via 10.0.1.4 dev eth0 </snip> I got my answer. Thanks. I guess I should have used "ip ro del 10.0.1.0/24 dev eth0". I used via as the scope link src was there. I wanted to get rid of the generic route for 10.0.1.0/24 via eth0 and replace it with a route for just 1 ip 10.0.1.1 (my router's ip) via eth0. Thus all packets meant for my LAN will go thro' eth1 while those meant for the router will go thro' eth0. I think I need to do a few more runs of the iproute2 doc to understand syntax pretty well. I was trying this so that I could use iptables for firewalling and tc/cbq/htb for bandwidth shaping out of my LAN without reconfiguring and gateway IPs on nodes. I was given to understand that a pure bridge will work with iptables. Further reading has enlightened me on that too. Looks like the bridging code now interfaces with iptables. Thanks for the help.
