Hi Ken, As far as I am aware, if a port is showing up as 'closed' instead of 'filtered', which i assume you mean when you say 'stealth', it means that it is sending a tcp reset packet to the tcp packet it received as apposed to just dropping the packet. I am not a networking guru but I would not class that as a bad thing as it is sticking to the RFC. Most firewalls by default drop packets that are not explicilty allowed, unless told to send a tcp reset, but most OS's will send a tcp reset if the port is closed. I hope this helps.

Hello all, I just joined the list and this is my first post to it. I am a networking noob and am not sure if this is something I should worry about or not. I just set up a Smoothwall Express firewall and later ran a Shields Up scan at grc. com It showed all ports as stealth except one, port 113, which it showed as closed. Shields Up gave my system a "failed" score based on that one port showing as closed. My question is, is this anything I need to worry about and, if so, how might I fix it? Thanks to all who offer their knowledge and help to those of us just getting started.
