I would like some help in completing my configuration. Basically I have an internet router (1841ISR) with 1 internal (LAN) connection and 2 internet connections. What I want to do is route specific traffic for 3 of my internally hosted services (smtp, https, etc) through one internet connection (fa0/0) and then route all other traffic through the unmanaged/dynamic IP ADSL connection (Dialer 0)....
I have attached the relevant areas of my config your review... I have tried some stuff with route-maps but I think i'm hung up at the area where you attach the route-maps to the NAT statement.
Do you see hits on your ACL?
I think it's because of the ACLs you are using to identify traffic.
Normally a client connects to the server on its wellknown ports(smtp,http etc), but the server talks back to the client on a port which the client used to initiate traffic. Client processes don't use well-known or registered ports as source ports instead client process use a temporary port number.
So assuming 10.10.1.203 is your smtp server, ACL should be something like this:
access-list 100 deny tcp host 10.10.1.203 eq smtp any
access-list 100 deny tcp host 10.10.1.203 eq smtp any eq smtp
