Wireguard VPN on UDM Pro behind Fritzbox - Handshake did not complete
Hello everyone
I have the following problem:
I have set up the Wireguard server on my UDM Pro, on the client conf i changed the endpoint to the ddns name who is configured on the fritzboxbut I get on the client "handshake did not complete".
My Setup:
ISP -> FritzBox 7590 -> UDM Pro (double nat)
Fritzbox: 192.168.2.1
On the fritzbox wireguard port forwarding to udm pro (192.168.2.10)
Udm pro: 192.168.1.1
Firewall subnet 192.168.120.0/24
Firewall rules on udm pro Internet in/out/local on any:any
Did anyone have an Idee what else is to do that i got an Connection with my VPN client?

Evening.
This does not add up:
Which IP is configured on the UDM Pro interface responsible of Wireguard?
Please make a drawing of your network.
Please post the Wireguard config with relevant bits anonymized.

Thats my configs:
Udm pro: 192.168.1.1, Firewall subnet 192.168.120.0/24
This statement is totally confusing. 
The Fritzbox-firewall coupling port is the UDM WAN interface which is, regarding to your description, 192.168.2.10.
So does this mean you have 2 local LAN networks on your UDM or is one just the internal Wireguard adressing?
Helpful for a focused troubleshooting here would be both, the WG server and client config file!
All further details and ToDos you'll find in the local Wireguard Tutorial!
