Personally, I think you should get on the phone with the TS folks at the firwall company. They could probably fix this quick.

Still no joy. -----Original Message----- From: Martin Blackstone [mailto:[EMAIL PROTECTED]] Sent: Monday, November 12, 2001 8:50 AM To: MS-Exchange Admin Issues Subject: RE: Moving Exchange server and Checkpoint FW1 I think you are looking in the right place. The FW. Since the mail works when the FW is down, the NAT and MX stuff is probably OK. Have you tried deleting all the FW rules relating to SMTP and recreating them? -----Original Message----- From: Charles Whitby [mailto:[EMAIL PROTECTED]] Sent: Monday, November 12, 2001 5:09 AM To: MS-Exchange Admin Issues Subject: RE: Moving Exchange server and Checkpoint FW1 Our ISP points our e-mail to an external address. Our Cisco router (via the magic of NAT) takes those packets and forwards them internally to thye correct address. This is working fine UNTIL we fire up the firewall. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Monday, November 12, 2001 8:02 AM To: MS-Exchange Admin Issues Subject: RE: Moving Exchange server and Checkpoint FW1 You have an MX record for your exchange server. Did you have that changed to point to the IP address? -----Original Message----- From: Charles Whitby [SMTP:[EMAIL PROTECTED]] Sent: Monday, November 12, 2001 6:56 AM To: MS-Exchange Admin Issues Subject: Moving Exchange server and Checkpoint FW1 Our company recently relocated, and we moved our exchange server from one subnet to another. We of course gave the Exchange 5.5 server a new IP address and made sure WINS has been updated on our NT4 network. Internal e-mail works correctly. We have a Checkpoint FW-1 protecting us fromt he bad guys. When the firewall is disabled mail to/from the 'net works fine. When enabled, no joy; can't send in or out. I checked the rules on the firewall (after making the appropriate address changes within its databases) and they look like they should work, but they don't. Any hints of other places to look?
