I have a vigor 2820 running with default firewall filters.

I recently installed the antivirus/firewall program Bullguard on a workstation and it frequently reports that it has blocked port scans from external ip addresses. I assumed that the 2820 with the default filter rules would block this sort of attack.

I created a filter to block all incoming traffic but whilst I could establish my usual vpn connection in to the vigor on the remote network, I then couldn't remote desktop on to any computers on the network

Am I missing something?

Thanks.
