Model: Deco X50-5G  
Hardware Version: V1
Firmware Version: Current

I want to connect a Deco X50G with a Fritzbox. Currently i configured the X50-5G as VPN Client which works, but only one way...

 

i can ping my systems at home, but i cannot ping devices in the x50 network.

 

is there any how to avaiable?

 

connecting to fritzbox is a no-brainer with wireguard. i guess it's only a smal thing.

 

configuring deco as VPN server leads to a config, which is refused by fritzbox to be imported...

 

what i want to do is the following

 

deco x50g with local internet link, fritzbox at home with local internet uplink, both sould establish a wireguard connection, so that all devices on both sites can reach each other. with two fritzboxes this works fine. the question is how to configure it between deco and fritzbox

Hi, thank you very much for your feedback.

Deco doesn't support site-to-site VPN.

So when Deco X50-5G is set as the WireGuard VPN clients, the selected devices can access the local network of Fritzbox, but not the other way around.

I think your Deco X50-5G uses CG-NAT, and the current IPV4 address is a reserved IP address. When it was configured as the WireGuard VPN server, it was behind the NAT firewall of the SIM carrier.

Best regards.
