That is incorrect. It would use whatever IP you assign them. There is no "advertised by WG". Wireguard peers are statically configured. In fact, I never suggested editing the WG config. So did you try? Eg, use 9.9.9.9: Assign all clients the DNS server 9.9.9.9 Then: config route option target '9.9.9.9' option netmask '255.255.255.255' option interface 'wg0' or config route option target '9.9.9.9/32' option interface 'wg0' You can choose any IP, so…
