I made what I thought would be a very simple change to our Cisco PIX firewall to allow mail and OWA access to our new Exchange 2007 server. We recently added a new Exchange 2007 server into an existing Exchange 2003 single server environment with the intention of decommissioning the old Exch 2003 box.
Here's more background:
I migrated all mailboxes from an old Exch 2003 server (LAN IP: 10.0.0.11) to a new Exch 2007 server (LAN IP: 10.0.0.9). All mailboxes were moved last night. On the LAN I can telnet to all the appropriate ports on the new email server (25, 443, 80, etc). From the Internet I cannot telnet to any of those ports.
I've attached the original config and the newest. All I changed was the line "name 10.0.0.11 MailServer" to "name 10.0.0.9 MailServer". I wrote the config to memory.
Can someone look at this config and tell me why email won't flow into the mail server from the web? I'm at a complete loss.
Thanks in advance!!
