We used to use snapgear as our firewall. There were port forwarding configured. When we sit in the office,and browse the web server using external ip address, it will forward the traffic back to internal server.
Now we are using cisco1811. Nat is configured too. From outside, there is no problem. But if we tried to use public address from the inside, the NAT did not happen.
It does make sense to me. But for consistence, how can we use the same ip for inside use as well as outside use.
I hope somebody can understand that.
