ruby on rails - Connecting to WSL2 server via local network

Question

I'm developing a rails app using WSL2/Ubuntu on my Windows 10 machine, which is great! The problem is I can't connect to my server from another computer in the same network.

For further clarity, I am running a Puma server on localhost:3000

I have tried the following:

1. Directly connecting to the IP address assigned to Ethernet adapter vEthernet (WSL) -> 172.26.208.1:3000
2. Directly connecting to the host machine's IPv4 address -> 192.168.0.115
3. Adding a firewall exception (using Bitdefender)
4. Binding the IPs above rails s -b 172.26.208.1 -p 3000

None of the above have worked thus far... What I'd like to do is:

• Test the website on another laptop/tablet/phone
• Use VScode from another computer

Is there anything I'm missing to at least see the website correctly? (and any comments on the VScode part would be appreciated)

See this video, it helped me:

netsh interface portproxy add v4tov4 listenport=<port-to-listen> listenaddress=0.0.0.0 connectport=<port-to-forward> connectaddress=<forward-to-this-IP-address>

for example

netsh interface portproxy add v4tov4 listenport=3000 listenaddress=0.0.0.0 connectport=3000 connectaddress=172.30.16.3

Microsoft has published a little bit of information about this on their WSL1 to WSL2 comparison page
