don't know networking, is any of this relevant?
The IPs and ports are up-to-date other than guild battle, if that's still a thing. The rest of the page needs a thorough review. I have to expect Mabi has fixed the need for nagle crap by now and there have been plenty of suggestions that adjusting MTU is bad. Also, any apps referenced here or on the page are probably out of date.
If anyone knows what they're doing and can clean up this page that would be great.
