Exchange server sending but not receiving emails
-
We've just moved our Exchange server from a TMG hosted service to PFSense and currently can't get Exchange users to receive emails from outside the network but they can send fine.
I've created firewall rules for port 25, 80 and 443. OWA can be accessed on 443.
If I turn back on the TMG server the Exchange server starts to receive emails again.
Here are my rules:

What am i missing?
-
please display the nat rules, youre likely missing an incoming rule there.
Edit: Are these rules on the WAN interface? -
Should be on the WAN interface.. right....??
Make destination your email servers IP address. LAN or whatever.. Port forward goes to what?

Just an update, I was able to get it working by setting the Exchange server gateway as the pfsense LAN IP.
Does anyone know the implications of using the pfsense IP as the default gateway as now it will try and route all class a/b/c traffic through pfsense? Do I need to make some static routes for them with the command shown below?
route ADD destination_network MASK subnet_mask gateway_ip metric_cost

I'd think you you want to use port 587 instead of 25.
