New SBS 2003 no external email and no external RWW
Posted on 2006-06-27
Just replaced my old SBS 2003 server with a new one. No migration, new setup. Only 1 NIC. I'm having the following issues:
1. Am not receiving external emails. Internally it works fine and am able to send out emails.
2. RWW does not work externally. Get "page cannot be displayed". Internally it works fine.
I have checked the hardware firewall several times for the port forwarding. Old SBS 2003 worked fine. All I changed was the name and IP address of the new server. I have tried changing the IP address in the rules and creating new rules but still no go. I have a hard time believing it's the firewall. I tested with telnet and I'm not even connecting internally. I think I may have a DNS issue.
The internal and external domains are named different.
How can I test the hardware firewall to see if port 25 is open?
Should there be a forward lookup zone for MYDOMAIN.COM and in the zone should there be "A" records pointing MAIL.MYDOMAIN.COM and WORKPLACE.MYDOMAIN.COM to the server IP address? There was this zone in the old server DNS.
Any help would be greatly appreciated. Thanks.
