I have the network topology in the following link please kindly refer it : http://www.gigapac.com/wp-content/uploads/2012/03/topology.png
- A site to site IPSec VPN is running between the two Cisco routers.
- The ASA firewall has two interfaces e0/0 (outside) and e0/1 (inside) and is currently configured to act as the default gateway for the PCs in the LAN.
- I have also added a route in ASA which routes 192.168.51.0/24 via 192.168.139.253 (inside) interface.
- The PC having IP address 192.168.139.21 cannot make RDP connection to 192.168.51.21. But when I set a static route in the PC and route 192.168.51.0/24 via 192.168.139.253 then the RDP session works.
I have also enabled the following command :
same-security-traffic permit intra-interface
But still no luck. Do I need to do "no nat-control" or do some static translations?
