Good morning, I am trying to use WireGuard. I can connect to the VPN, but I cannot access any websites. The strange thing is that if I open a website in my browser (Firefox) and then launch the VPN, I can browse the previously opened websites, unless I open links external to that site. Do you have any advice for me? Thank you and have a nice day.
Is IP forwarding enabled on your system?

Also check if Wireguard has a DNS that you can actually reach. Had this issue on my setup on the beginning. Lastly, set allowed IPs to 0.0.0.0/0
