Thanks for sharing. However, you may need to specify source CIDRs for the PostUp and PostDown hook iptables rules so that clients can access Internet properly.

For example, if subnet 172.16.77.0/24 WireGuard is dedicated for this WireGuard use case, specify it in the NAT rule ->
iptables -t nat -A POSTROUTING -o eth0 -s 172.16.77.0/24 -j MASQUERADE.

tried with udp2raw config

Server side:
udp2raw -s -l0.0.0.0:8888 -r127.0.0.1:443 -k "passwd" --raw-mode faketcp -a

Client side:
udp2raw -c -rserverip:8888 -l0.0.0.0:8887 --raw-mode faketcp -a -k"passwd"

and could got server and client ready
