I'm trying to install a new internet connection from a different ISP. In the process we are also getting a new external IP subnet. I would like to be able to route traffic on the new subnet via the new connection and anything on the old IP subnet through the old connection. I tried setting up a route-map to catch traffic on the the F0/0 interface from the new subnet IP range and send it out F0/1. I can see traffic matches for the access-list, but traffic doesn't appear to be routed correctly (can't ping anything outside). The default route points out the Multilink1 interface. I need to be able to route both of our external subnet ranges so we can transition over our devices from one WAN connection to the other.
Am I missing something? Is there a better way to accomplish this?
Here are the basics of my config:
interface multilink1
desc 2xT1 WAN link (old ISP 1)
ip address 65.xxx.85.74 255.255.255.252
interface f0/0
desc LAN interface
ip address 65.xxx.251.162 255.255.255.224
ip address 12.yyy.245.1 255.255.255.224 secondary (new subnet)
interface f0/1
desc 20MB metro-ethernet (new ISP 2)
ip address 12.zzz.104.206 255.255.255.252
ip route 0.0.0.0 0.0.0.0 65.xxx.85.73
access-list 150 remark Match all traffic from new subnet
access-list 150 permit ip 12.yyy.245.0 0.0.0.31 any
route-map 20MB-opteman permit 150
match ip address 150
set interface FastEthernet0/1 (also tried "set ip next-hop 12.116.105.205")
interface FastEthernet0/0
ip policy route-map 20MB-opteman

What happens if you do a traceroute ? - do you see the packets going out the correct interface ?
Can you post full config of router ?

Nevermind. I was able to figure it out. I think it was just a typo in my route-map command.
Thanks though!
