Getting kicked from Punkbuster Servers

im getting kicked from punkbusted Battlefield 2 Servers frequently because the handshake fails.

The log entry is:

Datum/Zeit :2007-09-02 22:34:37 Schwere :Mittel Melder :Netzwerk-Monitor Beschreibung:Outbound Regel-Verletzung (Zugriff verweigert, ICMP = PORT UNREACHABLE) Protokoll:ICMP Ausgehend Quelle: (my IP) Ziel: Meldung: PORT UNREACHABLE Grund: Netzwerk-Kontroll-Regel-ID =5

I’ve searched for a solution for this and found an entry in the PunkBuster FAQ.
It seems that there are some new components in the PB software.

I tried some rules in my comodo personal firewall for PnkBstrA.exe and PnkBstrB.exe but can’t get it to work :-
Any ideas?

Can’t be sure, but I think that the protocol should be IGMP, not ICMP as it is in the Network Rules dropdown in Comodo. They need to correct the spelling if that is the problem.
