no defined rule, but program can connect to internet... why?

i just installed net transport and my firewall security level is custom policy mode.
i started one file in dl manager (net transport) and firewall hasn’t asked me what to do. net transport connected to internet without any problems. it’s activity can be seen in “active connections”.
but in firewall>advanced>network security policy i can not find net transport (as it supposed to be as i haven’t defined rules for it). but how can it pass thru firewall then???
sorry for tarzan english

Have you tried setting FW, Advanced, Attack Detection, Misc, “Monitor other NDIS protocols” ?
