I have a Freebsd installation running VirtualBox on my local LAN behind NAT trying to connect out to a Scaleway VPS running Ubuntu 20.04.
Using Debian 10 the VPN connects just find and I can ping all interfaces and ssh between machines.
But using Freebsd, I cannot ping the local wg0 interface. However wg show appears to show the VPN connecting. All firewalls on Freebsd are off, and of course I have configured only one Endpoint as I'm behind NAT.
I'm not knowledgeable with Freebsd, so there may be something I'm not doing.
# cat wg0.conf
[Interface]
Address = 192.168.40.1/24
ListenPort = 51440
PrivateKey = <stuff>
# wg-quick up ./wg0.conf
[#] wireguard-go wg0
INFO: (wg0) 2020/09/29 02:13:45 Starting wireguard-go version 0.0.20200320

All looks fine to me...
# ifconfig -a inet
wg0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1420
options=80000<LINKSTATE>
inet 192.168.40.1 --> 192.168.40.1 netmask 0xffffff00
Opened by PID 28234
but when I try to ping I get no response
# ping 192.168.40.1
PING 192.168.40.1 (192.168.40.1): 56 data bytes
In FreeBSD would I expect a ping response?
I'm intentionally only showing one site.
Configuring the Peer makes no difference.
Thanks John
