Redundant ISP Links

Unanswered Question
Jan 8th, 2008

I have setup an ASA cluster to use Redundant ISP Links as show in the cisco example


http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a00806e880b.shtml


This works fine for outbound traffic, i.e. web browsing. However I would like to use it for inbound as well, connecting to a SMTP server. As I understand it there cannot be two static mappings to the same IP address, from the two ISP CIDR ranges. If I place a second IP address on the SMTP server to allow two mappings I cannot determine which address will be used as the source IP for outbound traffic. I believe this will screw up the connection.


Any ideas, assitance appreciated.
