Have a Pix 525 behind a router. I want to
remove the router and have the Pix 525 directly connected to the Internet. That means changing the IP address of the outside interface on the Pix 525. I have several Pix 501s that tunnel to the Pix 525. I don't want to change the config on
all the Pix 501 so they tunnel to the new
IP address on the outside interface on the Pix 525. Can I bring up another interface on the Pix 525, give it the old IP address of the outside interface, and have the remote Pix 501s use the non-outside interface on the Pix 525 as the tunnel endpoint?
