Routing port 80 traffic to DSL WIC on Cisco 2600 Router


Currently we have the following set up on our Cisco 2600 router:

2 WIC each with a T1 attached
1 DSL WIC for DSL backup

Both T1's are bonded for 3 up and down and if they both go down the DSL takes over for backup.

What I would like to do is keep the same setup, but for all port 80 traffic, direct it to the DSL for faster access.

Is this possible in the router? I hate paying for a DSL connection when it just sits there in standby.

So you want to route any tcp:80 stuff i.e web traffic OUTGOING through the DSL connection ? I just wanted to be clear as to your requirement.
if so, this was posted somewhere else on experts exchange, essentially you need policy based routing which the 2600 series does support.

Try something like this:
\\-- remove current default routes
no ip route interfaceX <-- replace as needed
no ip route InterfaceY <-- replace as needed
\\-- create two acls to define www traffic and all other traffic
access-list 101 permit tcp any any eq www
access-list 102 permit ip any any

\\-- create route-map with 2 conditions
route-map www permit 10
 match ip address 101
 set ip next-hop <DSL upstream gateway>
route-mdap www permit 20
 match ip address 102
 set ip next-hop X.Y.Z.X  <== remote end of T1

\\-- apply the route-map to the local LAN interface
interface Fast 0/0 <-- replace as needed
  ip policy route-map www
and there is a typo i think on the second 'route-map' statement.
