Hello, I hope you can help me with some configuration advice. I have:
-A single W2K Server in an environment, 1 NIC
right now
-Same server running Exchange 2000, SMTP only to
the outside.
-DSL Modem translates SMTP port 25 to internal
NAT address for Exchange.
-A small range of public IP addresses that is not
currently being used because the DSL modem is
doing NAT right now, and disabling the use of
those IPs.
We would like to put Astaro out as a firewall and allow only traffic over port 25 to reach the internal NAT address of the Exchange services. Essentially, we want to put Exchange out in a DMZ, and we are trying to figure out the best way to do this. Should we:
-Add a 2nd NIC to our server with another NAT IP, let Astaro do the NAT, and have Astaro route SMTP traffic to that IP only? We tried this initially, but had a devil of a time with the NetBIOS name responding to both IPs on the server, suppose we'll have to unbind it from the new NIC.
-Do it all through Astaro? Keep only one NIC in the server, and have Astaro create some kind of DMZ for only port 25 traffic?
Please excuse my shortness of detail, and thanks again for any insight you can provide.
Precarious
Isn't it most?
