At my old company we had an asa 5510 with a t1 connection and a DSL connection. Somehow we had SMTP and vpn route through the t1 and http etc through the dsl. I remember seeing the config and it was a really simple conf! But i cant figure out how it was done!
I have a 5505 with the sec plus, and i have 2 diff isp connections, I wanted to route specifficly HTTP&(S) and dns through one interface and all traffic out of the other, simple enough? but i cant figure it out! I know exactly how to do it with a router using route-maps....ugggg. I do remember another thing it did too! it would actually direct the dsl traffic over the t1 if the dsl failed, but this was not a backup isp config! (base 5510) it was like 2 type of default routes, i think..... I remember it was explicitly stating smtp and https over the t1 and w/e else over dsl.....
