Route

1、The default gateway between the vNAT and the TAP device is 10.8.0.0
2、If you need to run all (TCP/IP, ICMP, UDP/IP) protocol data through SkylakeNAT then you need to configure the following route (CMD/cli interface).

WIN + R (runas administrator) -> cmd

route add 0.0.0.0 mask 0.0.0.0 10.8.0.0
route add 0.0.0.0 mask 128.0.0.0 10.8.0.0
route add 128.0.0.0 mask 128.0.0.0 10.8.0.0

WinAPI operation route can be referred to https://github.com/liulilittle/SkylakeNAT/blob/master/SupersocksR/Net/Routing/RouteTableManager.cs

3、If you're only going to SkylakeNAT for an IP or IP segment, you can configure SkylakeNAT as follows
    1、route add 172.8.8.8 mask 255.255.255.255 10.8.0.0 (172.8.8.8 ~ 172.8.8.8)
    2、route add 198.18.0.0 mask 255.254.0.0 10.8.0.0 (198.18.0.0 ~ 198.19.255.255)

Usage

Must run the program as Administrator
Specify that the IP that the SupersocksR listens on must be an "Ethernet physical network card" (typically a RTL[Realtek] network card) that can access input or output traffic
