My company Scenario:
I have connected the branch office to main office using VPN.
Main office is running under domain environment and using a Watch guard as a firewall.
Branch office is running in a work group environment and using a Billion VPN Wi Fi router.
VPN has been set up between Watchguard Firewall (XTM26) and Billion Wifi Router (Bi Pac 8920nz)
VPN is working fine. I am able to take remote of all the computers located in to the branch office using "Microsoft Remote Desktop" from the main office.
I am not able to ping any of the branch office computers. I can ping branch office wifi router and network printer only. What could be the reason?
