Hello all, My network is currently using NAT with a basic sonicwalll pro 100 firewall. I have 2 new webservers to implement. i am going to purchase a cisco 515e. This is kind of my first time setting up webservers on a network. Is it better to set them on a DMZ or have it sit behind the firewall and have the ports forwarded? all advice is appreciated.

It is always considered best practice to put any server that is publicly accessible on a DMZ.

How many DMZs can the Cisco 515E handle? What do you think about this setup:

Internet<------>external router<------>Webserver(DMZ)<------>Firewall<------>internal router
<------>Network

The 515 can handle up to 6 interfaces, or 4 DMZ's

Internet
    |
  Router
     |
  PIX Outside           Whatever you want the DMZ's to be....this is just an example
            DMZ1 ----- Web servers
            DMZ2 ----- Extranet connections
            DMZ3 ----- Special purpose servers (VPN)
            DMZ4 ----- reserved for future use
   PIX inside
       |
    Internal network
       |
    Internal router ----- intranet WAN remote sites

Nice description! :0)  Here is a very stupid question though: Is it possible that I could hook a cisco switch into DMZ1 to host mutliple web servers?

Absolutely! You can connect any interface to a switch. You can have 1000 servers on any DMZ that you want...
