Hello Cisco Experts! I've recently taken over a new role from a co-worker and could really use some expert advice. I'm attempting to setup Outlook Web Access and a secondary MX record over at my failover datacenter. There I have a 5510 which already has an IP assigned by our ISP bound to the WAN interface. I purchased a new block of addresses on a different subnet that I'd like to use for OWA and a secondary MX record at my datacenter. I can't seem to bind more than one public address in a different subnet to the WAN interface which is how I thought this would work. I further read that the work-around is to use Proxy ARP and NAT. Being new to this I could really use some step-by-step help in configuring the ASA so the new addresses I have are properly forwarded to Exchange (OWA) and Websense (secondary MX). I can have Cisco support do it but I want to understand how this works so I can be more useful in the future. Many thanks in advance for any assistance!
