Network interfacing issues faced using WSL 2 (and fixes)

#wsl2 #lan #bugfixing #webdev

#1 - Memory not releasing back

It becomes overload to the system and eventually leading to Blue Screen of Death if not treated on time.

# only termination (still VM is alive)
wsl -t kali-linux

# shutdown
wsl --shutdown kali-linux

#2 - WSL2 network ports are virtual and cannot be accessed from LAN

# for port forwarding
netsh interface portproxy add v4tov4 listenport=8001 listenaddress=192.168.0.10 connectport=80 connectaddress=192.168.0.10

# for listing
netsh interface portproxy show all

# for cleanup
netsh interface portproxy reset

# or,
netsh interface portproxy delete

# ON and OFF
netsh interface portproxy add v4tov4 listenport=4422 listenaddress=192.168.1.111 connectport=80 connectaddress=192.168.0.33

netsh interface portproxy delete v4tov4 listenport=4422 listenaddress=192.168.1.111

You need to get Linux IP (use ip route). Check official docs for more information. Also, you can use NGINX with the following configuration:

events {}

http {
     server {

        listen 192.168.1.111:4422;

        location / {
            proxy_pass http://192.168.2.33:80/;
        }
     }
}
