I have configured IPSEC VPN between my branch office and HQ and able to reach the branch through HQ LAN and vice versa. Now I have to transport the internet from HQ for users at the Branch office using this IPSEC VPN tunnel but I am not sure how to do this. I use ASA at HQ and router at remote Branches.
