Trying to get e-mail and owa working through an RVL200 to an SBS2008 / Exchange 2008 server.
Started by opening ports 25, 80, 443 using the Firewall Access rules and pointing them at the server. NO mail got through and OWA would not work. Moved the server into the DMZ and all worked fine so definitely a router issue.
Someone else then opened the same ports under Setup>>UPnP and disabled the firewall rules. This appears to have worked. I noticed that he had also turned off remote management.
(Due to other issues there was a reboot just before these settings were applied)
My question is why would settings under UPnP work while firewall access rules would not?
Is there a recommended approach to opening up these ports.
