Issue

Looks like routing to default gateway is not working. I can get udp traffic from client to raspberry and viceversa but I can’t see any traffic between the client and the gateway or forwarded from the raspberry to the gateway. Handshaking is keeping the connection alive between wireguard client/server. Mine configuration is WireGuard running on default udp port, I dunno if the provider is blocking it, any chance to debug? Router is 192.168.1.1 Raspberry is 192.168.1.4 (static ip) DNS is raspberry pihole itself OS: is ubuntu server arm64

The amount of traffic is going up an down is like the DNS queries only.

This is a part of tcpdump
