Netcomm 1300NB DSL Modem Denial of Service

[Chris Rock <chris () kustodian com>]

There is an issue with the Netcomm 1300NB DSL Modem in regards to a Denial of Service attack. By sending off the 
following ping command in four seperate shells or windows the WAN interface on the Netcomm DSL Modem locks up and the 
device must be rebooted to get Internet Activity. The Netcomm ADSL Modem is given away commonly with new ADSL 
Connections.

ping -l 65500 -w 0 -t <IP of DSL Modem>

Open 3 new shells/cmd and paste it in again. Kill the shells and send a normal ping to the device and it is gone, until 
reboot.

The Netcomm 1300NM Modem series has no ICMP/Ping blocking from the external interface. There is no Netcomm solution.
