I need to config the openvpn in such a way that the client will be in the same subnet as the LAN. for example, the LAN is using 192.168.0.x, i want the client to be something 192.168.0.y. please do not challenge my request as there is a special need for this. this can be done on netgear nighthawk R7800 (TAP mode instead of TUN). however, seems i cannot make it work on this router (btw. initially i tried to post in router section and requested by forum to post here as the hardware has modem function).
