Port forwarding problem with Ipcop
I have a problem with port 25 on an Ipcop box. Or maybe it's not the port it self that's the problem. I have already forwarded port 20, 21, 22, 80, 443, 1701, 1723 + GRE for internal use on both the orange and green network. Everything have worked perfectly until now.. I'm about to implement a mail server and want's to port forward port 25 to a specifik IP on the green network. But when I do my RAS server can't be reased from Red network.!
(port 1701 + 1723) Anyone knows what the h... is going on.?
The mail server works perfectly when adding the port forwarding.
EDIT: Just tested if I could forward port 25 to orange network. Worked perfectly.
