I recently purchased a billion 5100 router. I have set it up to route certain ports to my server (vpn, http etc.) I decided to run a test on it from ( http://scan.sygatetech.com/ ). The majority of my ports are ‘closed’ but according to the site “This port has responded to our probes. This means that you are not running any application on this port, but it is still possible for someone to crash your computer through known TCP/IP stack vulnerabilities.”
On my router I do have several ports forwarded to my server. I want to know
a )how secure my network is
b )Should I install a software firewall onto my network pc’s (if so which one (preferably free))
c )*this is not related, but what ports do I need to open for VPN to work??
