Port Forwarding


Hi, I have a couple of questions, first I have a Cisco Soho 77 ADSL that I want to setup as a Web server in my PC. I tried using Dynamic DNS service www.dynu.com or www.no-ip.com and others, I think that my current config is Nat/Pat, I did a reverse mapping to my NAT, I added
"ip nat inside source static tcp 192.168.25.3 80 10.28.1.29 80 extendable" and still doesnt works, I think I need to do a port forwarding, but dont have CRWS configured. How does one set up port forwarding on the Cisco SOHO 77 router?

This is my router Configuration.

Current configuration : 1118 bytes
!
version 12.2
no service pad
service timestamps debug uptime
service timestamps log uptime
service password-encryption

end

The router doesn't have port forwarding configured so it just denies the connection. So I need to configure port forwarding.

Thanks for your help.

I take it this is the ip assigned to you by your ISP?
Thats a reserved for LAN adress. I suspect your ISP is doing NAT as
well. UIF so you will have to presuade your ISP to give you a ip address reachable from the internet or configure portforwading in their NAT as well.
