We had a firewall problem on an SBS 2008 network this morning and I had to switch a few things around.
At the moment I have only opened three ports open on the 2wire firewall:
110 - for mail to Blackberries and iPhomes
25 - for emails
3389 - for remote access to the server
All point to the local IP for the SBS server. but no mail is getting through to the exchange server.
I have checked Message Tracking and nothing is coming through.
Thanks in advance for any ideas.
