Thanks, this fix definitely worked and I can confirm this is the problem with my setup, has anyone already tried to implement a patch or a script to run on startup to fix this? New to the PfSense project and a big fan of wireguard, is there a github/ gitlab where we can submit issues/ fixes for this? [EDIT: disregard, it seems that the tunnel reset corrected the issue initially, although follow up attempts have been met with a working handshake but no flowing traffic, Might be easier to move to another VPN protocol at this stage]
