Digium Asterisk Appliance 50 AA50 Administrator's Manual page 92

SSH - Select the SSH checkbox to activate the SSH server on the
AA50. The default root password is digium. Enabling this option will
cause your unit to provide SSH access on both WAN and LAN inter-
faces, which can pose a security risk.
Note: It is suggested that you change the default root password the
first time you SSH into the AA50. Use the "passwd" utility from the
shell to change the password. Changing the default password will
increase security.
URL for Auto-Provisioning - The URL specified in this field is used
to enable auto-provisioning for Polycom phones. The default for this
field is http://0.0.0.0/phoneprov. The 0.0.0.0 will resolve to the IP of
the AA50 with the LAN IP for requests from the LAN ports, and the
WAN IP for requests over the WAN port.
The WAN tab is used to specify the settings which will enable connection
to the Internet, or to an internal, private network.
DHCP - The DHCP setting enables the automatic assignment of an IP
address to the Asterisk Appliance 50. This checkbox is selected by
default.
Enable GUI on WAN Interface - Select this checkbox only if you are
certain you want to enable access to the Asterisk Appliance 50 GUI
via the WAN interface.
Enable WAN Side Provisioning - Select this option to enable the pro-
visioning of Polycom phones connected through the WAN.
If you have difficulty obtaining an IP address dynamically, deselect the
DHCP checkbox and specify the IP address, Subnet, Gateway, and DNS
settings. This information should be available from your company
network administrator or Internet Service Provider (ISP).
