Wireguard not working, followed multiple guides.

[NetGobbler]

I am absoloutely stumped and lost, I would love some help if anyone could be so kind.


https://docs.opnsense.org/manual/how-tos/wireguard-client.html
I've followed this guide, twice, still no success.

I know for a fact, I messed this up the first time, because I neglected to copy, my public key from my Windows client into Step 3 (endpoint)
However I did fix that the second time,.



I've also followed this guide which seems significantly less complicated (to the point I suspect it's lacking some items?) which also, obviously didn't work.  A whole heap of items from the above guide are lacking for this one.

I understand I'm not really too skilled here but I mean I've had opnsense up and running for nearly a year, I've followed guides for forwarding ports, I've been working with computers 30 years, but this eludes me no end.


If I should be asking somewhere else, please let me know if there's a 'newbie' forum.

Without showing your actual setup (screenshots) nobody will be able to help you. Most likely: keys messed up? ;-) Do you ever see a handshake in the GUI?

[petersk]

Did you allow access to your DNS through for the IP address range?

Did you allow access to your DNS through for the IP address range?

I mean once it connected (it seemed to actually connect for the first guide)  I was simply trying to ping my NAS or opnsense machine - to no avail, via IP - not hostname, so I imagine DNS isn't the issue.

I /think/ there's a handshake, in the first tutorial (the block quote seems to imply it's connected and performing a keep alive)  but I actually don't know, where in the GUI to even check for a handshake.   I'll try again and see.

(That's an awful lot of screenshots but I'll try)

Ok I think I've got all the screenshots I can and anonymised them best I can.

I don't see an Endpoint configuration for Phone on OPNsense in those screenshots. Or the WG configuration on the phone itself

Sorry, thank you!

Endpoint:

Windows client (for testing, phone eventually obviously)

The Endpoint Allowed IPs are incorrect. See step 3 of the official guide. It should be a /32 within the /24 subnet set for the tunnel under Local

[chemlud]

The peer config on the sense:

- Allowed IPs the tunnel IP of the client is missing and 0.0.0.0/24 is more likely 0.0.0.0/0

Handshakes are in the GUI plugin for the Dashboard as well as in the WG part of the GUI under Status and Handshakes (unsurprisingly ;-) ).
