Firewall solution needed
Posted on 2004-09-23
I'm trying host about 10 - 12 websites on my Windows 2003 server. I have a single server that functions as a print / file / DHCP / exchange / web server. It has two network cards - a 10/100 and a 1000. Right now I think its set up very poorly because I was in a hurry. I have a cable modem connection with a block of 13 public IP addresses. I have a watchguard firebox soho 6. I have the external interface on the watchguard firewall setup for a static public ip. The firewall connects to a switch which the 1000 nic on the server plugs into and has a static internal ip of 192.168.111.100.
Now, where I think the problem is on the second 10/100 network card. I have assigned it about 10 other public ip addresses and its connected directly to the cable modem - no firewall. I don't see the point of having a firewall on one server nic and not the other, but I can only assign 1 ip address to the external interface on the watchguard firebox. Can this be right?? If it is right, who makes a similar firewall that will allow me to assign multiple external ip address's and have them NAT to different internal IP's on the server. Basically, I need to be able to host a bunch of websites, enable outlook web access for my employees, but keep all of my confidential information on the same server secure.
