moving a server from LAN to DMZ

[adam7979]

hi all,

i have a simple network setup: a PC acting as firewall, with three NICs, one to the ADSL (public), one to LAN, and one to DMZ.

Currently my email server (RH8, internal use only, "fetchmail" from hosting server) is located in LAN, 192.168.0.3, and now i'm planning to move it into DMZ, and allow public access into it (LAN users who work or need to retrieve email from home), after i upgrade it to CentOS 4.0. However, the DMZ is using ip address range of 172.16.0.X

all LAN user's email app is using 192.168.0.3 as incoming mail server as well as outgoing mail server, is it possible to "map" 192.168.0.3 to 172.16.0.3 thru the firewall?


Thanks

Adam

all right, i fix my own s with a dirty solution:

make my firewall listen on 192.168.0.3 and forward it to the new 172.16.0.3 ....
