That is a question for simple curiosity: In my LAN i make some hosts available by NAT entry in the DSL router for access from the Internet. That all works fine.
What i can never do is using from within the local network the WAN address to connect to my host. For example for testing if the NAT table works fine.
Ex. Local network 192.168.1.0/24, a host 192.168.1.10, my WAN fixed IP address 126.96.36.199, NAT port WAN 22 translate to 192.168.1.10 port 22.
And i cannot do ssh 188.8.131.52 when i use the same NAT'ed router to the internet.
Is this due to the NAT protocoll or type of connection that i have or anything else ?
