Title: Wireguard - Dnsmasq
Post by: JavierĀ® on September 23, 2025, 04:07:51 PM
Hello everyone, I'm trying to configure WireGuard using the IPv6 prefix I received to avoid NAT for IPv6 traffic. I created a WireGuard instance with the assigned prefix and a unique IP address, and automatically, in the Dnsmasq leases, the connected devices switch from LAN to VPN (strange).
VPN is the name of the WireGuard interface.

What am I doing wrong?

Thanks

If it is relevant, I only request the prefix and size.
And manually I configure prefix ID, interface ID
