http://www.dslreports.com/scan/ reported back on an ADSL modem router with 

TCP 80 is OPEN
TCP 254 is OPEN
TCP 255 is OPEN
UDP 67 is OPEN

this is not a webserver/server AFAIK and he doesn't telnet just web 
browsing and POP/SMTP email

AFAIK the firewall in the router is blocking all ports (you have to open 
them via a lan web interface) web and email are working fine, Zonealarm is 
not showing didily!!

Feedback as to how to deal with this report if indeed anything needs doing? 
How to close the ports or are they blocked "inside"

Device linking ADSL cable to LAN is a pseudo generic adsl modem router with 
Conexant firmware including the Free BSD version firewall.

Over to my (more) learned friends
