I'm not sure I entirely understand your dilema but it should be possible under 2.2. You need to use the iproute2 package and have an appropriately compiled Linux kernel. I've used policy routing in a few places and it enables you to masquerade/NAT as any address you like. ip rule add from 192.168.10.0/24 nat 1.2.3.4 If you router's default gateway is on an interface other than the one to which you wish to NAT then you may have to set up a custom routing table for that network. ip route add default via 1.2.3.1 table 192 ip rule add from 192.168.10.0/24 lookup table 192 nat 1.2.3.4 This has the effect of routing all your externally destined packets arriving from the 192.168.10.0/24 network to your 1.2.3.1 router with a source address of 1.2.3.4 ... 1.2.3.4 must actually be an address assigned to you Linux box. Note you will probably have to add throw routes for your local networks to the new routing table you created so that local traffic works correctly. We use this in a location with 4 different Internet connections (DSL/T1) and route different private IP servers out the different gateways ... it works very well. -- fraser campbell <[EMAIL PROTECTED]> starnix inc. tollfree: (905) 771-0017 thornhill, ontario, canada http://www.starnix.com/ professional linux services & products
