NAT issues

I am having problems with the following senario:

Router A

FA 0/0 10.1.1.1

FA 0/1 10.2.2.1

ip route 192.168.1.0 255.255.255.0 10.1.1.2

Router B

FA 0/0 (wan) 10.1.1.2

FA 0/1 LAN 192.168.1.0/24

Here is the issue,

NAT is running on router B (192.168.1.0/24)and is working fine.

From my local network, which sits off router A, I need to be able to access the 192.168.1.0/24 network.

The 192.168.1.0/24 can be accessed from the 10.1.1.0 or 10.2.2.0 networks.

From behind a firewall off Router A, I cannot access the 192.168.1.0/24 network. When a tracert is performed, it hits RouterA then nothing.....

Any advice on this situation?

Thanks

Re: NAT issues

I looks like routing issue

I dont see route back to 10.2.2.1

on router B try

ip route 10.2.2.0 255.255.255.0 10.1.1.1

Re: NAT issues

I will give it a try.

I can access the 192.168.1.0 block from router A, pings come back, if I set a PC on 10.1.1.0/24 or 10.2.2.0/24 it also works.

Re: NAT issues

What type of NATing you are using here.

Please keep in mind that if you want an outsitde network host to initiate a connection across a NAT device , the NAT should be static and the NATing address should be published.
