@selfhosted strange problem. I have a raspberrypi as vpn gateway. I have a reolink cctv. It emails me when motion. If i use openvpn, it works fine. If i use wireguard, it does not work. If i connect to the vpn gateway on my laptop, openvpn and wg forward the laptop traffic fine. The openvpn and wg is connects to the same commerical vpn service.
@AtariDump did a tcpdump, and dns is working, have self hosted pihole. It is really strange.
