I have a box on DSL, that is behind a NAT, mail server has a private ip address, I'm forwarding all the required ports
I have a example.com and a DNS entry of mail.example.com that points to a real IP address
188.8.131.52 (made up to protect the innocent) that is the public dsl address.
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
192.168.100.10 mail.example.com mail
First ? should that entry be nat's private address as it is, or should it be the public ip of my DSL.
Ok so here is my first problem.
I can "telnet localhost 25" and conect to the mail server, but when I "telnet 192.168.100.10 25" I get connection refused. I have iptables off for testing. And I can get web part of zimbra so I can connect to 192.168.100.10 to connect to other services just fine.
So what have I done wrong.
FYI, this is only temorary till I move the box to the datacenter. But I'd like to get it working and test zimbra before I move it.
