Folks, I have an urgent problem... I have a dualhomed host, two internet uplinks, with two internal networks, and I need to access some hosts from both of the links. Debian Woody, kernel 2.4.17, iproute2-ss001007, iptables v1.2.4 I did NAT from 64.x.x.131 to 192.168.x.x, and from 200.x.x.218 to 192.168.x.x. It works ok, except for something: I can't find out a way to force the packets DE-nated to 200.x.x.218 to go out by the 200.x.x.x iface, they all go out by the default iface, which is 64.x.x.x. I tryed with iproute2, these are my rules & routes: # ip ru l 0: from all lookup local 32764: from 64.x.x.128/26 lookup uunet 32765: from 200.x.x.192/27 lookup comsat 32766: from all lookup main 32767: from all lookup default # ip ro l table uunet default via 64.x.x.129 dev eth1 # ip ro l table comsat default via 200.x.x.222 dev eth0 # ip ro l table main 200.x.x.192/27 dev eth0 proto kernel scope link src 200.x.x.219 64.x.x.128/26 dev eth1 proto kernel scope link src 64.x.x.131 192.168.x.0/24 dev eth2 proto kernel scope link src 192.168.x.200 default via 64.x.x.129 dev eth1 But it ignores my source routes. It seems like it chooses the output interface before prerouting (?), before de-natting, where the source address is 192.168.x.x, and in that moment I don't know how it will be de-natted Can anyone help me???? As a side note, I also cannot setup loadbalancing combining ip route nexthop with iptables MASQUERADE. I do: # ip r d default # ip r a default nexthop dev eth0 via 200.x.x.222 nexthop dev eth1 via 64.x.x.129 and then: # ip r l 200.x.x.192/27 dev eth0 proto kernel scope link src 200.x.x.219 64.x.x.128/26 dev eth1 proto kernel scope link src 64.x.x.131 192.168.x.0/24 dev eth2 proto kernel scope link src 192.168.x.200 default nexthop via 200.x.x.222 dev eth0 weight 1 dead nexthop via 64.x.x.129 dev eth1 weight 1 The "dead" flag stays there, and never uses the 200.x.x.x route.. Do you know why it could be? - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
