Hi folks,

I'm running kerio firwall 6.0.11 and

have the following specific rules for the silent hawk application I'm running:

FW( ==> vsf( allow tcp(51090-51210)
FW( ==> vsf( allow udp(51090-51210)
FW( ==> broadcast( allow tcp(51090-51210)
FW( ==> broadcast( allow udp(51090-51210)

vsf ( ==> FW ( allow tcp(51090-51210)
vsf ( ==> FW ( allow udp(51090-51210)

with the firewall running SOMETIMES the app responds to vsf request via tcp IP and sometimes it doesnt SEE RED AREA lines 451-454.

with the firewall stopped, the app consistently responds to vsf request SEE GREEN AREA lines 465-475.

The app vendor says he has not seen this kind of problem with any other firewall!

Has any one seen this kind of a flakey/intermittent response on tcp/ip services running on a kerio firewall on windows 2000, xp pro or 2003 server?

any help/suggestions would be greatly appreciated!
