We have Exchange 2007 and I am wanting to start using Outlook Anywhere and Exchange Active Sync from the WAN. I want to use SSL on both but I cannot find anywhere to change the port for this? Are you forced to use 443 for both services? The exchange server is behind a firewall that has webservers listening on 443 already....what is the usual course of action to allow this....? Is pretty much everyone just putting their mail server on another network with separate firewall? Thanks in advance.

not sure what kind of fw you use. If you have multiple Public IP addresses, it's easy to setup.

Problem is the firewall is behind a WAN aggregation device that takes 4 WAN IPs and then and forwards them onto the firewall. Is there a way to do it in this scenario?

So the WAN aggregator forwards traffic from all 4 IP's to the same firewall? Is there anyway from the firewall to distinguish which source IP the traffic came in on? If so, you should be able to setup a static NAT to the interal IP for the exchange server if this facility exists on the firewall? It all depends on your hardware. Shaun

Hi, Please just open 443 port for the both services. http://www.isaserver.org/tutorials/Publishing-Exchange-2007-Outlook-Autodiscover-2006-ISA-Firewalls.html Thanks Allen
