Dual ISP with 1721!

Dear all,

i have a 1721 with a serial connection to my first ISP and a second ADSL connection to my second ISP!

Behind the router is my firewall!

So i put the second isp in order to route the http traffic through it!

My configuration file is :

Inter S0

Connection to 1st ISP

ip addr A.B.C.D1/28

Inter e0

Connection to 2nd ISP

Ip addr X.Y.Z.W/30

ip nat outside

ip policy route-map ISP2

Inter fae0

Connection with Firewall

Ip addr A.B.C.D2/28 (this is an address from my 1st ISP)

access-list 101 permit tcp A.B.C.D/28 any eq www

access-list 102 permit tcp A.B.C.D/28 any neq www

route-map ISP1 permit

match ip address 102

set next-hop ip A.B.C.D1

route-map ISP2 permit

match ip address 101

set next-hop ip X.Y.Z.W

I did that but non www traffic goes through ISP2

Any IDEAS?

Thanks in advaced !

Re: Dual ISP with 1721!

Route maps need to be applied to the inbound interface, the firewall interface in your case.

Assuming you have a single default route pointing to ISP1, you'll only need 1 route-map to send traffic matching access-list 101 to next-hop X.Y.Z.W. Everything else will follow the default route to ISP1.
