I Need a firewall recommendation.

I am setting up two 2003 standard edition web servers. I am thinking I would be better off with a hardware firewall between these servers and the internet.

The only services they will need to run are: smtp 21 pop 110 htp 80 https 443 ftp 21 And remote desktop 3389 (I think)

Since there are two servers the firewall must have some way to route incoming requests to the proper server. For example lets say server's

1 domain name was domainTest1.com and server's 2 domain name was domainTest2.com. Requests for port 80 on the domain domainTest1.com would be routed to the IP of server 1, and requests for port 80 on the domain domainTest2.com would be routed to the IP of server2. The same thing is required for the other services/ports.

1) Do I need a hardware firewall if I am running 2003 standard edition? All unneeded services will be turned off including windows file sharing.

2) What hardware firewall you anyone recommend? I was looking at the cisco 501 and 506e, but the traffic on these servers is small, counted in the hundreds of hits a day, not thousands.

Thanks.
