Hi,
I am trying to accomplish a routing task and need a little guidance,
I have Cisco 887 ADSL Router that is our network's default gateway. There are several NAT entries for different servers and ports etc.
The issue i have is that the ADSL connection is being overloaded by general web browsing, so I want to have that handled by a different router with a faster cable connection.
If is set the default route 0.0.0.0 to point to the cable router then obviously the NAT entries become useless.
I set up a new access list with the servers in it that have port forwards, and then made a route-map connected to that list so that any matches are force to use the Dialer0 interface on the 887 as default instead of the cable router.
In the access list, the servers are listed as "permit ip host xxx.xxx.xxx.xxx any"
The route map matches IP addresses listed, and sends them to the Dialer0 Interface.
This all works fine, however we have one server that is both an SMTP server (Trustwave Mail Security server) and is also a Proxy server for our network, so i need to send SMTP traffic through the Dialer0 on the 887, but i want web traffic to go through the cable router.
I can get the server to send SMTP correctly by using the line "permit tcp host xxx.xxx.xxx.xxx any eq 25" but it will not receive SMTP.
Are there any tips to getting this to work? I know the alternative is to move the proxy to a different IP, but i'd rather do it through tht router.
Cheers.
