Nat Questions

[alfil2k08]

Hi all,

I have a problem with a router cisco 837 on my work. That is the configuration:

1 DSL Wan Interface named ATM0.1 with the external ip Ex: 80.36.25.24 and NAT outside, and the ethernet interface with internal ip ex: 172.26.0.254 and NAT inside.

The nat config is:

ip nat inside source list 102 interface ATM0.1 overload

ip nat inside source static tcp 172.26.0.1 8081 interface ATM0.1 8081

That's work fine if i try to connect with my browser from the external(ex: my house) to my work to the port 8081.

But, doesn`t work if i try to connect from my computer in the office using my external ip and port on the browser. URL ex: http://80.36.25.24:8081. My computer have the ip 172.26.0.53.

Wich are the correct configuration for that work correctly??

Im not sure I understand what you are saying.

Are you saying that you have no Internet access through that router when you use a machine that sits on the local internal LAN?

If so, have you configured access list 102 correctly? Does it include the IP address of the machine you are using?

No, I have acces to internet correctly. The is when i try to connect from the local lan to the http://80.36.25.24:8081. If i use http://172.26.0.1:8081 work fine. All traffic is really on the local lan.

Many thanks,
