Hello,

I have AVG Internet Security (Multi-Device).
I have been checking in a Windows laptop my wifi with the Network Inspector from AVG.
Acorrding to it I have the following application ports on my router open, but I have been checking myself and with my Internet Service Provider(Movistar):
SSH (22) => Not opening
DNS (53) => I understand should be open for resolving names but I don't see open
DHCP (67) => I undertand should be not open and I didn't open
HTTP (80) => Not open
NETBIOS (137) => I have to check but I think is not open
SNMP (161) => I have to check but I think is not open
HTTPS (443) => Correct is open
SSDP (1900) => I have to check
UPNP (49152) => I think is not open but I have to check

Basically according Network Inspector from AVG all the above ports are open but the ones I have checked many of them they are not. Is this a bug or am I doing anything wrong?

Thanks, César
