help with wireguard over udp2raw

nordine

hi, this my problem : wireguard over udp2raw won't work ,there is no handshake
my config
in server :
[Interface]
Address = 10.0.0.1/24
PrivateKey = key=+
ListenPort = 51120

just iptables open ports..

PostUp = /etc/wireguard/up.sh
PostDown = /etc/wireguard/down.sh
[Peer]
PublicKey = key=+
AllowedIPs = 10.0.0.2/24

in client :
[Interface]
Address = 10.0.0.2/24
PrivateKey = key=+
[Peer]
PublicKey = key=+
AllowedIPs = 0.0.0.0/0
Endpoint = 127.0.0.1:5666
PersistentKeepalive = 25

Case 1 : just between Wireguard - work :
(Endpoint = vps-ip:51120 <--> Wireguard work great without udp2raw)

Case 2 : just between udp2raw - connected:
in server
udp2raw -s -0.0.0.0:5111 -r 127.0.0.1:51120 -k "passpass" --raw-mode faketcp -a
in client :
udp2raw -c -l127.0.0.1:5666 -r vps-ip:5111 -k "passpass" --raw-mode faketcp -a

Case 3 : all together with Endpoint = 127.0.0.1:5666 I lose connection
Endpoint = 127.0.0.1:5666 <--> wont work

at start ( wg-quick up wg0) I can see :
[#] ip link add wg0 type wireguard
[#] wg setconf wg0 /dev/fd/63
[#] ip -4 address add 10.0.0.2/24 dev wg0
[#] ip link set mtu 1420 up dev wg0
[#] wg set wg0 fwmark 51820
[#] ip -4 route add 0.0.0.0/0 dev wg0 table 51820
[#] ip -4 rule add not fwmark 51820 table 51820
[#] ip -4 rule add table main suppress_prefixlength 0
[#] sysctl -q net.ipv4.conf.all.src_valid_mark=1
[#] iptables-restore -n
[#] ping -c1 10.0.0.1
PING 10.0.0.1 (10.0.0.1) 56(84) bytes of data.

--- 10.0.0.1 ping statistics ---
1 packets transmitted, 0 received, 100% packet loss, time 0ms

[#] iptables-restore -n
[#] ip -4 rule delete table 51820
[#] ip -4 rule delete table main suppress_prefixlength 0
[#] ip link delete dev wg0

So I think there something with route table needed IN My COMPUTER , I'm not very good in routing,
thank you for your help...
