Re: Windows security question, or general security question
as long as your router firewall doesnt allow connection in on those certain ports, and doesnt have a port forwarding map then ya you should be fine.
Of course i say that and a firewall appliance we have at work said it did this, but then there was a flaw in software which allowed certain MS ports through by default AND DID NOT SHOW THE TRAFFIC!!! which made for fun when we were trying to figure out what all the port 445 and 139 traffic was. Patch fixed it, but as president 40 said, "Trust, but verify"
