[clug] iptables help

[Andrew]

Hi All!
        I don't normally like asking for help like this, but I am away from home and in a hurry ;)  I was hoping on solving the following problem....

I have a local network with 2 DSL connections, one is a 1.5Mbit/256K and the other a 512K/512K - I want to pass all http (port 80) traffic through the first link (1.5/256) and everything else through the second (512K/512K).

The first connection is terminated as "ppp0" on a linux (debian) router.  The second is terminated on a hardware router (built in NAT).

The debian box has 3 ethernet interfaces

eth0 - LAN (10.10.10.0/24) - with an ip of 10.10.10.1
eth1 - Used for the 1.5Mbit connection (ppp0)
eth2 - Used to communicate with the hardware router (10.10.9.0/24 - the hardware router has the address 10.10.9.2)


So - ideally - *LAN* --->  *DEBIAN BOX* ---
                                                             If port 80 ---> ppp0
                                                             Everything else ---> 10.10.9.2 via eth2

Any examples/help/pointers will be greatly appreciated.

Many thanks,
                  Andrew
