Site to site VPN only working for one site at a time
-
I need to setup a hub and spoke site to site VPN. I followed the instructions here: https://docs.netgate.com/pfsense/en/latest/recipes/openvpn-s2s-psk.html to create one with a shared key. I'm able to get the VPN working for each of the remote sites BUT, ONLY ONE AT A TIME works.
The only deviations I made to the configuration instructions is to change the tunnel network from /30 to /24 AND I set the "Concurrent connections" to 10.
Currently I only have 2 remote sites that need to connect to the home office, but will be adding another in the future. I suspect the problem has to do with using the same Shared Key, but I can't for the life of me figure out how to get both remote sites working simultaneously.

I just wanted to follow up on this, in case anyone else runs into the same problem.
The way I was doing it is for a 1:1 VPN. I solved it by following these instructions: https://docs.netgate.com/pfsense/en/latest/recipes/openvpn-s2s-tls.html
A bit more complicated setup, but it's now working.
