Reduce MTU of the WG interfaces to accomodate for overhead. See
calculations of by how much.

I wonder what's this IP range, is this some VPN service? Squatting on
unassigned IPs within 2000::/3 seems like a very bad practice. If they wanted
an imaginary GUA for their NAT66, I'd suggest something like 66::/16 instead.
