I  have 1841 cisco router with  ver 12.3
and I am looking detailed syntax on how toadd NAT translation for  local static ip node ip nat
192.168.0.12 so that it can communcation with remote public IP sites.

this is what I have for anohter IP
source static tcp 192.168.0.166 654.55.xxx.xxx extendable
access-list 5 permit 192.168.0.166
access-list 120 permit tcp host 192.168.0.166 any

this assumes you have another ip address to nat with and the second ip address would be 654.55.xxx.xxx


conf t
source static tcp 192.168.0.12 654.55.xxx.xxx extendable
access-list 5 permit 192.168.0.12
access-list 120 permit tcp host 192.168.0.12 any

ip nat inside source route-map POLICY-NAT interface Dialer1 overload
ip nat inside source static tcp 172.25.0.2 456 interface Dialer1 456
ip nat inside source static tcp 172.25.0.2 9999 interface Dialer1 9999
!
ip access-list extended NAT
 permit ip 172.25.0.0 0.0.255.255 any

route-map POLICY-NAT permit 10
 match ip address NAT

The above is what i have  on my router
do you have a pool of addresses as you can change the interface command to a pool
do you want to nat an ip or just a port?
