Hi, I need some help here interpretting the results of a port scan on a router/firewall. Behind the router there is a mail server, a web server, and a terminal server. There is a VPN tunnel set up. And remote administration is enabled (dumb, but not my choice). The common ports I am familiar with and understand why they are open. Open ports: 25/tcp open smtp 80/tcp open http 135/tcp filtered msrpc 137/tcp filtered netbios-ns 138/tcp filtered netbios-dgm 139/tcp filtered netbios-ssn 443/tcp open https 445/tcp filtered microsoft-ds 593/tcp filtered http-rpc-epmap 1723/tcp open pptp 2555/tcp open unknown 3000/tcp open ppp 3389/tcp open ms-term-serv 5554/tcp filtered unknown 8080/tcp open http-proxy 9996/tcp filtered unknown Thanks.
