We had a remote VPN connection issue. The remote users behind ASA need to access servers behind VPN concentrator. Right now VPN session could be established. But the remote users with the private IP address like 192.168.x.x are not able to get access to servers. But they could if remote workstation was assigned public IP address directly. It looked like the issue was from NAT of ASA. Could you give me some specified advice where I should check? Thanks a lot!
