I have an new 851 that I configured for use with a web server and email server. I set up NAT to allow certain ports through to access the services running on the server (mail and web).
I also set the firewall settings to "High".
It allows ports 80, 25 and 110 through, but it does not allow other non-common ports through, such as 2525 or 2552. I see the commands in the NAT address table for all of the allowed ports. They all look exactly the same; like the web service (port 80) and the mail service (port 25). However, the other ports (2525 and 2552) are not allowed through.
Is ther anything I can check to see why?
Do I need to lower the firewall settings? I want High security.
