21.7.1 Missing WireGuard kernel support error

[giangi]

Hello,
I'm trying to get a s2s working. One at the moment does not have a public port, but I don't think it is the culprit here.
On siteA(vb) wireguard starts normally, config below

Code Select Expand

interface: wg0
  public key: xxx
  private key: (hidden)
  listening port: 51821

peer: xxx
  endpoint: publicIP:46107
  allowed ips: 10.50.20.0/24, 10.100.0.0/24
  latest handshake: 9 minutes, 41 seconds ago
  transfer: 328 B received, 25.38 KiB sent
  persistent keepalive: every 15 seconds

SiteB (cp) screenshots
and from shell /usr/local/etc/rc.d/wireguard start gives

This issue happened on both instances, following previous discussions I reinstalled wireguard and site vb at least has it configured now (or so it seems), but site B has issues.

Any help appreciated

It's not an error. The WireGuard authors can be pretty weird... their kernel module is still experimental and we have used the Go implementation since 2019.


Cheers,

Thanks for the insight!
So then what could I possibly go about and troubleshoot on site B that does not start the service (even from the dashboard)?

Remove .50.0/24 from the endpoint
