Pretty certain I linked the new one. Shows created January 2022 and last updated May 2023.
EDIT: Weird the last updated cell does show 2019, but looking at the docs metadata through Google drive shows Jan 2022 and May 2023. You may be right though, this could be stale.
Dude still seems to be updating this; though, there doesn’t look to be a column detailing port forwarding. Maybe look into a few of these that look good?
