- Existing option `WIREGUARD_MTU` , if set, disables PMTUD and is used - New option `PMTUD_ICMP_ADDRESSES=1.1.1.1,8.8.8.8` and `PMTUD_TCP_ADDRESSES=1.1.1.1:443,8.8.8.8:443` - ICMP PMTUD now targets external-by-default IP addresses - New TCP PMTUD (binary search only) as a second MTU confirmation and fallback mechanism. - Force set TCP MSS to MTU - IP header - TCP base header - "magic 20 bytes" 🎆 - Fix #3108
