I would like to set up a hardware firewall, specifically a SonicWall 100 with a DMZ. My existing configuration may make this difficult though. Does anyone have any recommendations as to how I can accomplish this?
I have 5 separate physical sites, each with a DC w/DHCP,DNS and global catalogue. All sites including the routers are private addressing and routed to only one site with an IP gateway. I have a limited number of valid IP addresses to use for my DMZ. Now physically, I only have one circuit coming into each site. At site 5 (my Gateway) I still only have one circuit coming into the building.
Addressing as follows:
Site 1. router:LAN 172.20.140.254 into my DC: 172.20.140.1
Site 2. router: LAN 172.21.140.254 into my DC: 172.21.140.1
Site 3. router:LAN 172.22.140.254 into my DC: 172.22.140.1
Site 4. router:LAN 172.24.140.254 into my DC: 172.24.140.1
Site 5. router:LAN 172.23.140.254 into my DC: 172.23.140.1
WAN 2xx.xxx.xxx.xxx ? 2xx.xxx.xxx.xxx
Site 5s circuit only comes in on one Ethernet circuit so I don?t know how to configure my router to the sonicwall without adding another complete circuit for the firewall.
Does this make any sense? HELP
