Greetings,
I started off with what looked like a straight forward and simple install, but apparently I am missing something here.
I have a DSL conntection on eth0 to the firewall and then eth1 to the mail server (which is also doing NAT for the internet users)... People's mail clients are setup to either use the ext IP address (or DNS lookup for name) of mail server. But now it's behind the firewall.
DSL Router (216.xxx.xxx.254)
--> Fire wall (216.xxx.xxx.88)
--> Fire wall (192.168.2.100) -- out
--> Mail srvr (192.168.2.1)
--> Mail srvr (192.168.1.100) -- local network
The server appears to be receving outside email and connections (SMTP & POP3) okay, but when you're inside the network, NO GO with the DNS lookup for the server. We don't want to use the internal IP because several users take their laptops out of the office and don't need to change their IP addresses every time.
Under Network:NAT I have ---
Any -> eth1_Interface__ / POP3 None Mail Server
Any -> eth1_Interface__ / SMTP None Mail Server
whereis [eth1] is the "216.xxx.xxx.88" & [Mail Server] is the "192.168.2.1"
Other servers are able to send SMTP just fine to the server, and external users are able to POP just fine as well, just the internal folks are having problems.
Any ideas on what I'm not thinking of?
