Iceman,
wingate firewall can stealth ur system. i've tested it thru grc's shields up service.
u can make ur wingate stealth if u go to Extended Networking> Port Security> select Connections from Internet, and remove any incoming connection for TCP & UDP. and make sure Default action is set to "Deny"
this setting is best if ur not allowing/running any inbound services e.g. web, ftp, etc...
now for the outbound issue, u cud ask d qbik team regarding
NetPatrol (havent used it). i think what ur after is something like a "component or process control" w/c will block or prompt any outgoing activity. for that feature u cud check on the free versions of
Sygate or
Outpost. both r compatible with wingate but DO NOT install both.
note: for trouble-free installation, disable ur anti-virus.
