First, sorry if this is a noob question.
Recently move from DD-WRT to tomato firmware, and this is amazing.
Before, I use 2 routers, 1 main router to ISP, and another one just for OPENVPN for my guests.
I realize tomato has this function that I can target internal IP range who uses the vpn service and the rest just use my regular IP from my ISP.
Can anyone guide me step by step how to set it up? Or do I have to setup a VLAN?
Thanks in advance.
