troubleshooting Question
Cannot nat across Site to site VPN
asked on
I have network A as 10.201.10.0/23 and it is connected to network b 128.1.0.0/16 via site to site VPN on cisco 5505.
This is working as needed, but I need just one host on network A to be natted from 10.201.10.6 to 128.1.1.5 when it reaches network B.
Here is a jpg of the configuration and the configs for both router A and router.
