We working on SFS2x - without tuneling everething ok

if we enable tunneling - tcp work fine, but InitUDP give us error (success false)

same time tunnel udp direct sending works ok

nc -ulvp 9934
echo "test" | nc -u 127.0.0.1 9934


smartfox server see this pacckets too:
Discarded UDP packet from *.*.*.*:33225, reason: Packet truncated. Expected: 28528, only got: 2

but connectios still faile from sfs2x client to sfs2x server
