Hi there, I am needing some help with a Vigor 2800.
We have a new Exchange Server setup, All ports are opened that are needed.
Everything checks out on the server side however port 25 is being refused.
I have opened the ports on the router, Even setup a call filter and still no joy, And hence no email.
how do I fix this?.

is 25 used any where is in open ports or even in port redirection

2800 are pretty old units now, does it have the open ports option as well as port forwarding? I find this option it better than the port forwarding

also what firmware is it on?
there was NAT change from Release 2.6.4.1

2800 is more reliable than the 2820 and 2830 ( i've had all 3 and my 2800 is my reliable backup when the newer one fails ) going to try 2960 next
