Thank you for your interest, and your advice!
- I though of that and tried uninstalling the program - but as i thought it
didn't change a thing.
I hoped it would but no no.
- And it doesn't change a thing if i create the rule for the p2p-program as
a portspecific or a applicationspecific rule.
Port scan detection in NPF2003 just isn't as "touchy" (easy triggered) as in
NPF2002e.
But it has increased it's priority to TCP/IP connections and packets. And
therefor it blocks some of the traffic i actually wants - because of a NON
SYN / NON ACK packet in the traffic to and from p2p-clients/servers...
Too bad - but u can't get it all.
I actually considered "format c:" due to the fact that also Sygate Personal
Firewall seemed to do the same.
I have a ghost of the server with NPF2002/NAV2002 and i applied the image
and rebooted. And NPF2002 would detect any scans and allow the p2p-traffic
just fine. At the same time i would have to check the rules i've created for
onlinegaming to play MOHAA or Q3 (just to try some games) on the online
serves.
I upgraded to NPF2003/NAV2003 and everything was wrong again ( i didn't
upgrade, but uninstalled the prog's and installed the new ones.) No port
scan detection, able to play online without permitting it, and bad
connection on my p2p program.
And that kind of left me with the feeling that it wasn't some local thing
that has went wrong on my system or hardware. It's just the way NPF2003
acts!
So now i'm considering a refund of the money i spent on NPF2003 - or just
swicthing it to a years license on NPF2002.
Don't know yet! I'm still waiting for Symantec to come with a response. Have
you noticed that they have posted a message on their support site saying
that they get so many responses from users, that they have had to increase
their delay in answering mails. Propably due to the great amount of
questions and mails from little me :o)
(?) or not...
