We have a hub and spoke architecture:
HQ - PIX515, Cisco 3662 Router
Location1 - Cisco 1600 Router
Location2 - Cisco 1600 Router
Location3 - Cisco 1600 Router
Location4 - Cisco 1600 Router
Each location is connect to HQ via a Point-to-Point Full T1.
Each location is on a diffent subnet (e.g. 10.100.X.X - HQ, 10.1.X.X - Loc1, 10.2.X.X - Loc2, etc.)
We have a Security Camera Workstation at each location, that we would like to be able to access from the outside via http.
I have setup a public IP for the HQ site, and can access HQ's security cameras from the outside.
I would like to be able to access the other workstations from the outside via public IP's, as well. How can I accomplish that? How would I NAT across different subnets?
