You need a combination of iptables and iproute2 to do what you want because
routing is based on it's DESTINATION address and you need to route on your
SOURCE address so it uses a different route depending on which source IP is
in the packet..
Refer to this page which is sort of what you want BUT not exact. It'll give
you some ideas...

Subject: How to bind 2 WAN 1 LAN ?
Dear all...
I'm a Chinese and I don't think that my English is well .
But I have a big problem in use IPTABLES .
I've looked all the documents and FAQs , but I can't find a solution to
solve my problem .
At last I decide to ask you in my poor English ...^^||
I have a Linux server (Turbo Linux7.0 in kernel 2.4.9-3) to be my NAT server
.
I have make it running iptables-1.2.2-6 .
It have 3 NIC(Network interface Card) eth0.eth1.eth2 .
I have 1 LAN and 2 WAN interface they are 192.168.1.0/255.255.255.0 and 2
ADSL (one of my ADSL is pppoe another one is static IP) .
Now I want to bind thy all in my NAT server .
I rty to cut my LAN to 4 part are 192.168.1.0/255.255.255.192 &
192.168.1.64/255.255.255.192 & 192.168.1.128/255.255.255.192 &
192.168.1.192/255.255.255.192 .
That I wish the preceding 3 part go out and in with the pppoe ADSL (ppp0)
and the final part go through with static IP(because they are my servers) .
My biggest problem is in Linux I can't set the default gateway otherwise the
ppp0 will not work .
But if ppp0 is working I can't find who to make my final part
(192.168.1.192/26) go through the eth0 out or aome in...-.-"
I have do my best to explain my problem .
If you can't understand my question maybe can find somebody who know my
English or can talk in Chinese will better .
Sincerely yours
thanks a lot...^^
