I had one of those sitting in a drawer for years. I think i did get OpenWRT on it at one point. Eventually it just stopped working altogether, but i felt like i got more than my money's worth out of it. Even brand new that router cost next to nothing.

Funny enough i have the same multimeter too

The 841N works with OpenWRT. But AFAIR pretty much an EOL device with not much flash/ram.

If this thread is about the same model then yeah.

OTH I have a DIR-612 somewhere which is just chugging. I do need to add some ip dilters, but not less the enterprise would pay me.

:) wait until somebody read it.. its one vibe coding session away from done..

I've LOLed too but just an idea of a router FW in a memory safe language... is awfully convincing.

the one that i was trying, omarchy.

You can use snap or brew or build from source?

snap is a Ubuntu thing, nobody else uses it. Even Ubuntu users don't want to use it.

Nobody uses brew outside MacOS.

tio is in the AUR. Recent controversies aside, it's as easy as installing a regular package. But maybe GP doesn't have 10GB to install the entire build chain.

Presently it seems to be unlikely to find an inexpensive (I settled for a MikroTik model when replacing my mom's router. It almost fits the criteria. I can even port forward via SSH on it.

The one thing it won't do natively? IPv6 6RD, the cursed legacy ISP junk CenturyLink has for IPv6 on DSL or, according to some posts I encountered looking for a solution, their rare fiber runs.

So now it has a script I found online, triggered to run every 10 seconds because the PPPoE interface doesn't provide an 'on change' event hook. If the IPv4 address has changed the script tears down and puts back up the IPv6 address on the 6in4 tunnel and lease blocks.
