We have OWA set up on a computer in our DMZ. I beleive the only change I had to make on it was inform it of the new WINS server address so it could find our Exchange box.
We have a Cisco 2500 series router connecting us to the 'net that is also NATing our exchange box. Our public e-mail address is resolved by our ISP to the WAN port of this router: the router then takes anything to do with e-mail, ports 25 and 110, and sends them to the proper internal private address (via our Checkpoint FW1). We don't have any kind of VPN set up so I can't help you there. Hope this helps. -----Original Message----- From: Diane Beckham [mailto:[EMAIL PROTECTED]] Sent: Friday, November 30, 2001 11:34 AM To: MS-Exchange Admin Issues Subject: FW: Change Exchange IP Oh good, so I can pick your brain huh :-) I'm in process of doing this and it's not working. What settings do I need to update to use OWA through a Firewall and a NAT. I read a MS doc that says to static route 2 ports on the exchange server, how does this affect my internal LAN users? Would this also affect my telecommuter users who VPN/PPTP into my email server?

Also, we have a web application that enables a potential customer to send e-mails to our CS department from the web site. If you have something like that you may have to update the SMTP settings in IIS (or whatever you use) on your web server. Also if your Exchange box is running the IMS service and you're being NAted by a firewall or router you will need to update those settings. Just recently did this, so the memories are fresh (but almost healed) Hope it helps. -----Original Message----- From: Bao, Gang [mailto:[EMAIL PROTECTED]] Sent: Thursday, November 29, 2001 2:16 PM To: MS-Exchange Admin Issues Subject: Change Exchange IP We plan to change the IP number of our EXCHANGE server. Is there any thing that I should be care of? I know changing the name of Exchange will create problem, but haven't heard any on changing IP. I would be grateful if you could give any advice and comments. Thanks.
