This is the old configuration. I have few confusion on this configuration. I have not seen ip nat inside on lan port and ip nat outside on wan port. And, I am not also being able to see the nat transalation with ip nat tranlsatioin command. When I execute ip nat translation I am able to see only the static translation but not the actual translation. Can you please explore about the nat configuation on this.
Now I want to add new ISP link on int fa0/2. If I add ip nat inside source list 7 interface FastEthernet0/2 overload command it is not being able to nat/pass traffic, why ? However if I connect a new router on fa0/2 and do the new nat setting with the same ip address of the new ISP in the new router I can see the nat translation data but my connection becomes very slow. Is this due to double natting. In the same connection if I shut down the OLD ISP connection my net connection from new ISP also fails. I will not be able to pass traffic through lan to internet, but I am able to ping from the new router.
I have not run ospf on the new link. I passed the traffic through static routing, what goes wrong, don't know.
I could not figure out what is the problem. Please, anybody help me in this matter.
First off, you didn't do NAT on R1841 for sure. It would be done only on PIX. Why? You were configuring old style NAT so you have to tell the router with "ip nat inside/ip nat outside" command. That's why you got nothing from "sh ip nat trans". Your router is fine. So no need to chain a new router to do NAT.
What do you want to do? Back up link(new ISP)?
If you want to do IOS NAT load-balancing, you can read the following document to get ideas.
