Re: Meeting THIS WEEK, July 10th, 2025! Topic: ?TrueNAS? Pi Kiosk displays?

by Tim Keller

I recently bought for my pi5 an actual cooler amd a hat that'll let me connect a m.2. I've hinted at setting up a zulip server and other stuff on it and then serving it over a tailsacale funnel. Time to put actually do it and present it.. So, I guess we've got a topic for August! Tim. I am leery of the allegiances of any politician who refers to their constituents as "consumers".

I use dyndns for my stoffel.org domain, so I have a couple of records in there, two are dynamic DNS which means the router at the remote location will send out updates if the WAN site IP changes. This makes it nice to get home via SSH if need be. What I'd like to see is a discussion on setting up and using wireguard to access home system(s) or networks from remote locations. I started playing with it, but got bogged down and never made any progress. I'm using OPNsense as my home firewall. And of course testing remote access is a pain. I've got wireguard on my phone, but haven't made the testing part work quite yet.

Something like Tailscale Funnel might meet your needs with CGNAT. https://tailscale.com/kb/1223/funnel You would need a cheap VPS to act as the funnel entry but those are fairly inexpensive these days. -------- Original Message -------- On 7/9/25 9:22 PM, Kevin Stratton via WLUG wrote: > I am interested in a pihole as well.
