Hi everyone!
I'm still pretty new to security and firewalls and such, and I'm having a problem wrapping my head around a couple of concepts. Here's what I have- I have a stand alone email server behind an Adsl router (with 4prt hub). The router is set to pass-thru (nat and firewall disabled). 1 port goes to a firewall device, and my LAN behind that. 1 port goes to my Email server, a Win2k box (hey, quit lookin at me like that). I've got a handful of fixed IP's to work with. Here's what I'd like to do- Keep everything the same BUT- put an OpenBSD box in between the router and the email server (protect the snivelling email server). So, I builts me dis purty OpenBSD box from the broken bodies of mine enemies past (a Dell Dim XPS V350 with a bad video card). Put 2 Nics in the beast. Lovely. Now, I have an IP from my block of 5 registered currently for my email server. I'm not certain if- I want to assign that IP to the OpenBSD firewall, and use NAT and/or RDR to pass on SMTP traffic on port 25 to the email server. Yes? No? Maybe? Am I a shame on my species? --------------------------------------------------------------------------- ----------------------------------------------------------------------------
