Static NAT and Dynamic NAT

Here is my simple config example


server, 10.1.1.1--------10.1.1.2 F0/0 router f0/1 11.1.1.1--------------outside world


router

int f0/1

ip add 11.1.1.1

ip nat outside

int f0/0

ip add 10.1.1.1

ip nat inside


ip nat inside source static 10.1.1.1 11.1.1.1  ---> map all tcp/udp ports

ip nat inside source static tcp 10.1.1.1 23 11.1.1.1 23   --> map only tcp port 23 for telnet


Hope this helps.

If you post more detail with how servers and routers are connected, then I can give u more specific example.
