LAN access with WSL2

[wickedwzrd]

LRR Version and OS
LRR Version: v.0.7.5 - Underground
OS: Windows 10 v2004

Bug Details
I am unable to access the reader on my LAN. I currently have LRR running on my home server and I tried to create an inbound rule for Karen.exe on any port and specifically 3000, but was still unable to access it from any device on my LAN.

I was scouring the closed issues and could only find that Mojolicious default config sets network to http://*:3000.

I would assume that LRR should work out of box over LAN so I am unsure as to what the issue may be.

Another note to add is that I am running LRR with WSL v2. I just tested switching back to WSL v1 and I have no issues connecting to the server. It asked me to allow perl access to private/public networks with the file location being %appdata%\roaming\lanraragi\distro\rootfs\usr\bin\perl

I noticed that when running WSL v2, LRR creates an ext4 image, while WSL v1 create a rootfs folder under the Distro folder.

WSL2 currently has some issues related to localhost access by other machines: microsoft/WSL#4636

For now I'd recommend you stick to WSL1 until said issues are fixed by Microsoft.
Although you can try to hack around the problems if you really want to: https://stackoverflow.com/questions/61002681/connecting-to-wsl2-server-via-local-network/64986363

Seems like a firewall issue. Try creating an inbound rule for all programs to allow connection on port 3000 and see if it starts working.

I think it specifically has to do with making your firewall rule only allow Karen.exe, because when I test on my own device and configure the rule to allow only Karen.exe through port 3000, it breaks and I also become unable to access my server.

e: as you both confirmed, it is a WSL2 bug. But if you configure an open rule on port 3000 while on WSL2, it works fine.

@huntrshado I noticed that while using WSL1, it creates a firewall rule for perl and not the karen.exe. However since WSL1 is easier to access the root folder so that I can edit my theme I will stick to that for now.

Since there's no real fixable issue on my side, I'll be converting this to a discussion so that others can see it if they run into trouble w. WSL2 installs. Glad you got it sorted out!
