[Fixed] Weird Wireguard issues I could use some help with. (lemmy.procrastinati.org)

I've hit a wall with a weird Wireguard issue. I'm trying to connect my phone (over cell) to my home router using wireguard and it will not connect.

  • The keys are all correct.
  • The IPs are all correct.
  • The ports are open on the firewall.
  • My router has a public IP, no CGNAT.

The router is opnsense, I have a tcpdump session going and when I attempt a connection from the phone I see 0 packets on that port. I am able to ping the router and reach the web server sitting behind it from the phone.

I have a VPS that I configured WG on and the phone connects fine to that. I also tested configuring the VPS to connect to my home router and that also works fine.

I'm really at a loss as to where to go next.

Edit 2: I completely blew out the config on both sides and rebuilt it from scratch, using a different UDP port, and it all appears to be working now. Thanks for everyone's help in tracking this down.

Edit: It was requested I provide my configs.

opnsense:

It definitely not connecting. I get no handshake stats on either side and my tcpdump shows 0 packets to try and even initiate the tunnel.
