Hi,

There is another router beforethe AX1800,but this will be the case on the location where to be used also and on that location I have no control on the ports. Besides when I do use the WireGuard from my device it is working. Connected via de AX1800 and also via the router before. The AX1800 is making connection. I see it is connnected.

There is no router in front of the Wireguard server.

Only thing which seems not ok:
On the server end I can see this:

endpoint: xxxxxxxxxxxx:51820
allowed ips: (none)
latest handshake: 39 seconds ago
transfer: 1.07 MiB received, 2.23 MiB sent

The settings on the AX1800 site are:
(Client setup)

[Interface]
Address = 192.168.33.3/32
ListenPort = 51820
PrivateKey = xxxxxx
MTU = 1420
DNS = 1.1.1.1

[Peer]
AllowedIPs = 0.0.0.0/0
Endpoint = SERV-ip:51820
PersistentKeepalive = 25
PublicKey = xxxx
