I have a site to site VPN setup between two USG20-VPN's.

Headquarters -
Branch Office -

I also host a VPN for mobile users at each office.

Mobile to Headquarters Tunnel -
Mobile to Branch Office Tunnel -

Computers in each office can reach each other ( -, but I would like a mobile laptop connected to the Branch Office Tunnel on to be able to reach computers on the Headquarters network (

Thank you.
