Hi, Hardware is Asus RT-N66U with Tomato RAF Firmware v1.28.9014 MIPSR2-RAF-v1.3g K26 USB configured as Gateway connected to internet with static IP. On my local network i have a computer running a VPN server (L2TP). VPN connection works perfectly on local network. I have forwarded UDP 500, UDP 1701 and UDP 4500 to my VPN servers local IP address. Can anyone tell me what else i need to do to use my VPN server from WAN? Thanks.
