My issue is rather simple: How do I configure my setup, so that my WSL (2) instance (ubuntu) could access and use a proxy server served using Burp Suite on the same physical computer, but on the Windows side?
Currently I am getting connection refused, whatever I do. The proxy obviously works fine if I test it in windows.
The proxy is setup to redirect localhost:3001 --> localhost:80. This is where it gets a bit tangly, as the localhost:80 server is in fact running on the WSL instance too.
So basically, I would like a program, FFUF in this case, on WSL to be able to send a request through my Burp Proxy which is on Windows. The proxy then redirects the request back to WSL to the apache2 server that is running there.
WSL (FFUF) --> Windows (Burp proxy) --> WSL (Apache at :80)
I believe there is something I am missing regarding localhost and what is localhost in what case.
localhost from Windows seems to work to reference services running on WSL, but I am not sure it works the other way around...
I have tried using localhost, 127.0.0.1, and the LAN IP of Windows as mentioned in the virtual WSL network. No luck from WSL side yet.
My apache is setup to listen to 0.0.0.0:80
