Ah… that makes sense. I need to firewall these ports ASAP.
x220:~$ sudo nmap 121.7.219.77
Starting Nmap 6.40 ( http://nmap.org ) at 2014-03-17 16:54 SGT
Nmap scan report for bb121-7-219-77.singnet.com.sg (121.7.219.77)
Host is up (0.015s latency).
Not shown: 996 closed ports
PORT     STATE SERVICE
22/tcp   open  ssh
53/tcp   open  domain
80/tcp   open  http
2000/tcp open  cisco-sccp
Nmap done: 1 IP address (1 host up) scanned in 4.25 seconds
Is there a guide to doing this is WebFIG I wonder? Surprised this is not the default, to block all incoming ports.

The default firewall is dropping any new connection from WAN (default WAN is ether1).
