maybe someone around can give me a hint:
when i access the packet filter live-log, i can find various entries that are blocked. i´m quite happy with that, cos i defined a very hard line with the packet filters - HTTP, HTTPS, DNS and SMTP are allowed, anything else goes to the blackhole.
i pasted an example of yesterdays log (my LAN is in the 10.x.x.x-area, 10.0.0.254 is my internal AD-server with DNS, IIS, SQL and Exchange on it). what packets are filtered here ... ?

i guess, the system doesnt slow down, when it has to block a few packets, does it?
