We are trying to configure a Cisco 1841 with basic NAT.
There is an inside pool,lets say 192.168.1.* which gets translated to and outside pool of 64 IP's. Lets assume outside range is 126.96.36.199-188.8.131.52
The outside Ip's must be distributed randomly to the inside ip's.
What I want to configure is NAT inside to outside. For now this works but the incoming connections from the outside pool get translated to inside, even when the connection originates from OUTSIDE.
I want to block incoming connections and allow only established.
How is this done?
