Advanced Options
HTTP Port Number
This determines IP Switch user interface port. By default the LAN port number
is
80
. If the port is changed, you will also need to change the manner in which
you access the switch via a web browser – i.e. If the port is changed to 82, then
to access IP Switch user interface, the user must type:
http://x.x.x.x:82
(where
x.x.x.x is the IP Switch's LAN IP address as shown in Utility).
NOTE: Remote Power Switch will reboot when these settings are
changed.
STUN Server
STUN is a standardized network protocol to allow the device to discover its
public IP address when it is located behind a NAT. Disabling STUN will do the
following:
a. Prevent Google Talk
“GET IP”
command from returning the
WAN IP
b. Email notification cannot show the current
WAN IP
c. Dynamic DNS server cannot acquire
WAN IP
Default is stun.I.google.com:19302
