I cannot connect from an external device to the DAppNode. I can through in my own network. The UI shows me “No NAT loopback, external IP did not resolve”. Fritzbox 7530 does not have this feature. I tried to add the public and internal IP to the DNS rebind protection exceptions in the router network settings. Does not work. Any suggestions?
There are several ways to connect to your dappnode:
DAppNodeWifi
Local network discovery
Openvpn
Wireguard
I assume you are trying to connect to your dappnode using either of the VPN methods (Open vpn and wireguard). In the wireguard method there is a credentials called “Local credentials”. These credentials have been designed to solve NAT loopback issues, could you try with them?
Also make sure you have opened ports and mapped to your dappnode (enable UPnP in your router), you have a view available at support > ports to scan the status of your ports.
