Hi all and thanks for lots of good reading on SNB.
I have been running a 2 site home network for a few years using OpenVPN as the connection between the two sites and as a personal internet access VPN which has worked well enough for us. Changes in hardware and software have occurred from time to time and, as long as it all kept going, I haven't worried too much. This year Site B moved to FTTP and a BT SmartHub2, plus I started using a PiHole there, but all the key functions seemed to survive the changes for several months, until some of them stopped! Stepping back and looking at the overall configuration, I think that there are some flaws but would really appreciate a sanity check on the design so that I can fix what I have got and then move on to some more changes.
Below is a tabulation of whats where, how it is setup and what it does. When everything worked, I could access all the expected interfaces at Site H (web, SSH, Ping etc); now, I can access the Site H router over OVPN as usual but cant reach the Device 1 server at all (it works as usual locally). In concept, I had intended to divide the 192.168.5.x network across the two sites but I see now (orange text) that I have glitched on implementation at some point; is this my only problem?
In case it helps, when I ping 5.223 over either a TCP or UDP tunnel I get a reply from the tunnel IP saying that the destination host is unreachable.
Have a good weekend.
