help to run udp2raw+tinyfecvpn ??

[isslam95]

hello,

i tried to
run udp2raw on server side by this command udp2raw -s -a -l0.0.0.0:8855 -r127.0.0.1:5000 (tinyvpn port) --raw-mode faketcp
and tinyfecvpn by this command tinyvpn -s -l0.0.0.0:5000 --sub-net 10.0.0.0 --tun-dev 100

and at client side udp2raw -c -a -r serverpublic ip:8855 -l127.0.0.1:3333 --raw-mode faketcp
and tinfecvpn tinyvpn -c -r127.0.0.1:3333 --sub-net 10.0.0.0 --tun-dev 100

the udp2raw tunnels are connected but tinyfecvpn aren't connected

do i need setup iptables ???
