Take a look through the NAT configuration examples:

After you have gone through these links, if you have any specific questions, re-post to this forum.

Here are several links to good NAT documents.

Static NAT and Dynamic NAT

http://www.cisco.com/en/US/tech/tk648/tk361/technologies_tech_note09186a0080093f31.shtml

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.
