Here is a follow up to everyone's replies.
First a clarification. The servers are dual xeon 2.88 machines so they are overkill as it is. All the services listed will be running on ONE of the servers. It will have one smtp/pop email server (Rockliff Mailsite) serving up multiple emai/web/ftl domains each domain with different IPs. The machine that is being replaced by this new one already has multiple web sites and email domains as described - so I already know how to do all this on one machine, but thanks for the informative replies anyway? The other server is running an app that uses one "weird" port, lets say port 1234 and remote admin.

----- I talked to the sonicwall folks and for a "low end" router the TZ170 looks pretty serious for a great price. And it will handle everything I need to do here and the ability to filter spam/malware at the firewall level (Macfee engine- would prefer the nod32 engine tho) is a great feature. I am almost certainly going to go this route. Thanks for the tip!

----------- You said - "do you really want to allow POP to the server through the Public connection?" Well yes. My company has a domain name that has emails associated with it and I have users that need to read their email. I have had pop 110 open to the public for years now. Am I missing something here?

------------------- In response to my statement:
All unneeded services will be turned off including windows file
> sharing.
You said: "Are you sure? and incidentally, do you need to disable anything at all if you're servers are safely behind a good firewall?"
Well here is why. These two machines will physically be on the same LAN behind the firewall. I don't need file sharing between them. So I was thinking that if one was compromised it would be better to turn off windows file sharing on both machines to limit the possibility that the compromised machines could be used to hack the second. What do you think now that is clarified?

------------------- You said: Not the way he described. 1 outside IP address, 1 port (port 80) being natted to two different IP addresses - which one it gets natted two depending on the URL that was requested. Not to many firewalls do layer 7 aware natting like that.
Sorry for the somewhat vague first post. Each web site/ ftp site will have DIFFERENT IP addresses.
------------------------------------------------------------------------------------------ So, right now it looks like theTZ170 unless further comments tell me better.
This was my first post to this group. It rocks! Thanks everyone?
