From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

[SOLVED] still cannot open a transmission port, what am I doing wrong? (lemmy.ml)

os: xubuntu 24.04

firewall: ufw

torrent program: transmission

On transmission I opened port 51401

On a terminal I executed sudo ufw allow 51401, which opens both tcp and udp ports for both ipv4 and ipv6. This is called forwarding, right?

I'm following https://github.com/transmission/transmission/blob/main/docs/Port-Forwarding-Guide.md but apparently I still don't get it

ETA: thanks for your input, issue has been solved

No, you need to forward from your router as well.

Internet -> router -> machine -> firewall

You've only allowed the firewall on this machine to allow that port through. Forward that port from your router to your machine's IP and port as well.

turns out this was the right answer all along

Well, at least you got it working.

then how come I've always torrented without editing the router?

I've used privoxy, can that be the reason?

[–] forbiddenlake@lemmy.world 13 points 5 months ago

You can still torrent without forwarding a port, for example by only making outgoing connections. But that may limit your speed, and figuring out forwarding should help.

Your client may have set a UPnP request that your router respects...hard to say. You didn't post any router config info, so it's hard to say what your environment looks like or was previously working. UPnP is frowned upon for security reasons, so it's best to just forward if in doubt.

I was still figuring out the right commands but thanks for your input
