I have already installed zimbra in a new server, but it is in a LAN with a private IP address, there is one gateway that has one public address and is doing NAT, but i have a problem, with port 25 i have no problems connecting from outside, but with pop3 when i try to connect from outside it gives me this error:
-ERR POP3 Access denied
If i connect from the LAN, i have no problems at all, in fact, the problem isn't only with pop3 from outside, but with 80 too (with this one, it simply doesn't connect)
I guess the problem isn't related with zimbra since i can connect it from the LAN, maybe the problem could be in the NAT??
Thanks in advance guys!
