freerouting VS portmapper

step 1: find a java project you want to compile. For the purpose of this post I'm using this one: https://github.com/freerouting/freerouting

I wanted a wireless crkbd, so I took petejohanson's ultralight corne mod and modded it even further — I added MX/Choc hot socket mounts. I used Freerouting app to wire the PCB automatically. It doesn't look pretty but DRC doesn't report any big issues.

The best thing to happen to KiCad was skidl [1] paired with freerouting [2]. You can spin a board in so little time it's insane. In the future I will be looking to automate even the parts placement too.

P.S. If there is interest I will look to document my workflow.

Running the excellent newly-multithreaded Freerouting under arm64 OpenJDK JRE 17.0.1 makes my 14" M1 Pro produce a whooshing sound that's really quite pleasant.

so far Autoroutering (specifically Freerouting) has never made any mistakes that weren't caused by me incorrectly connecting pins or placing components too close.

If you're just looking to do something simple like host a game server on your pc the easiest option is port forwarding with upnp if your router has it. This eliminates any fuckery with networking, all you have to do is enable it in your router and use a software that can open ports via upnp, i personally use portmapper.

You can use UPnP PortMapper. Source code/Download. All you need is Java and that's it. Hope this helps.

Check if UPnP is enabled, if so, use that to open port 80: https://github.com/kaklakariada/portmapper

Ok, so that shouldn't be hard to test, right? So I set up a test PC and run portmapper (https://github.com/kaklakariada/portmapper) to try uPnP to open ports. To test if they're really open, I use ncat on both ends. Doing that, with both udp and tcp ports worked fine: ncat allowed a two-way conversation from OUTSIDE the network to the PC on the inside. So, uPnP works, right?

Are you talking about this? https://github.com/kaklakariada/portmapper No, the issue seems to be external. Between my ISP, the domain services and the SSL certificate provider. I honestly dont know much more beyond that. Locally I can access the server through the new port I changed it too (2443).

Maybe not exactly this solution, but I need to start by asking SOMETHING 😆. I have a ps4, and would like to use remote play outside of my network, to do this ports 2925~2927 need to be forwarded. UPnP us enabled, and it is supposed to do it by its self, but it is only opening port 2927. I do not have access to the router, and cannot manually specify forwarding rules. I CAN however use portmapper (here) to open ports. I am on windows 10. I don't know the exact standards of UPnP, but i am unable to open a port to another IP besides my computer's. The idea i have atm (i know this is probably a long and round-about-y solution) would be to have everything received on port 2925~2957 just be passed through. Better ideas are welcome 🤣.
