Dear Guys, I need help with L2TP IPSEC Vpn setup. Wish to connect to my home network from outside and able to access my LAN computers and NAS etc as if I am connected to the home network i.e 192.168.1.x. Currently I cant even get any internet connection even though I can connect successfully. Not sure what is wrong. Any help is much appreciated. Thank you in advance.
