Host SOFTETHER server. You can range port forward local IPv4 on your routers of SOFTETHER NAT server Default gateway/DedIP and Local IPv4
Of course the Local IPV4 range of softether server would be limited to 192.168.1.1 - 192.168.255.255 and not to use 10.0.0.0 and someone may have same ipv4 local range on default network so that would cause problems when connecting too. If public dedicated IP of internet provider doesn't work as default gateway and address. try use same default gateway as the internet provider on softether NAT enabled server or separate device in computer to same default gateway as host of that server, redirect 0.0.0.0 of the host machine or 127.0.0.1 or local IPV4.. IF THAT DOES NOT WORK.. DISABLE ALL ROUTERS AND JUST USE MODEM WITH ETHERNET THAT WILL DEFINITELY OPEN PORTS FOR SOFTETHER SERVER?
BECAUSE MANY THIRD PARTY PROGRAMMABLE APPLICATIONS BLOCK INTERNAL IPV4 DETECT YOUR VPN.. SOFTETHER IS UNDETECTABLE.. PUT A LIMITED SPOTS AND BETA OF IT.. WOULD TAKE 2 DAYS TO SETUP FOR WEB ON OFFER AND THE SERVER
SOFTETHER NO ONE FINDS AS VPN.
