Network Interface Setup

Not applicable

I have a rather unique issue in that one of our internal networks is still on a public set of ips.  I can't switch it over at the present time, but I am having a problem figuring out how to get the PAN to work for me on this network.

My current setup is as follows:

Router off campus -> Sonicwall (same public ip on wan and lan and this ip is used as our gateway address for local machines) -> PAN (vwire to vwire) -> Internal network.

I want to get rid of the Sonicwall, but can't figure out how to setup the PAN to use the same public ip # on both ports. 

Let's pretend like the network range I want to use is -  I want the PAN to be on both ports.  Because I have to put in subnet ranges when I setup the L3 interfaces on the PAN I'm not sure how this would work.

Any help is appreciated.

What you would do is configure the PAN with the same addressing as the Sonicwall. At cutover time you would move the cables from the Sonicwall to The APN and clearthe cache of the upline devices.
