we have an asa 5510 with software 8.0. We have to Internet Lines, 1 16 Mbit ADSL and 1 4 Mbit SDSL. Internal Users should use the ADSL for faster downloads so the default gw is the ADSL. VPN should use the SDSL. This isn't the problem, i can use a routing entry with the option tunneled.
But now the difficult: The static Pat for some servers in the dmz should use the sdsl line because of the faster upload and multiple ip-addresses. Is there any way to manage this with the asa? Packets can go through the sdsl-interface and are forwarded to the server, but the answers will go through the adsl-line and therefore have a different Ip address.
Any ideas, how to solve this problem?
