ASA 5520 Redundant Links Inbound/Outbound



Ok here's what I want to do but I'm not exactly sure how to do it thus
far. On our ASA 5520 we have two "Outside" interfaces that come from
separate ISP's and we have multiple statics available from both of
those ISP's. I have a DMZ and INSIDE interface also. The webserver and
two DNS servers are located in the DMZ. Our Exchange server is on the
inside network for obvious reasons. I want to have one IP from each
ISP nat'd to the exchange server and webserver. Please assume I have
followed this document for my primary/backup ISP setup
http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a00806e880b.shtml
I would like to keep my current setup for failover of outbound traffic
in the event of a failure and add inbound access from both ISP's.
Thanks for any suggestions.
