I have a 1721 and a 1720 connected through their serial interfaces over a T1 connection. The internet is on the Fa0 interface of the 1721 and the Fa0 interface of the 1720 is in my LAN. Previous to this we had a Linksys router connected right to the internet. I had a server in the DMZ of that router so that when I hit the public IP address the server would respond.
Now that we've gone to this new set up I have lost the DMZ ability, Is there a way to configure these routers to either forward ports to a specific IP or to put an internal machine in the DMZ.
The way it would have to work if this is possible is to put the 1720 router in the DMZ of the 1721 and the internal machine in the DMZ of the 1720.
Is this possible.
Any configs or suggestions would be appreciated.
