Placement Behind a Firewall

LifeSize recommends that you place your system behind a firewall and block, at minimum,
the following ports:
• 22 (SSH)
• 23 (Telnet)
• 80 (HTTP)
• 443 (HTTPS)
If you require these ports remain open, ensure that you change the default administrator and
command line interface passwords to be very secure. For information about changing the
default administrator password, refer to the LifeSize Video Communications Systems
Administrator Guide.
For information about changing the command line interface password, refer to the LifeSize
Automation Command Line Interface document available on the Support page of
www.lifesize.com.
