This is how for the ST585v6... maybe it will work
Assuming windows operating system
Open a command prompt.
now type...
telnet 192.168.1.254
You will be asked for a username/password
[By default the username is Administrator and the password is blank.]
At the prompt type the following commands:
{Administrator}=>service system ifadd name=PING_RESPONDER group=wan
{Administrator}=>saveall
{Administrator}=>exit
