The end-user must configure the following settings according to the local environment.   NOTE:  Most 
settings on the web configuration pages are set to the default values. 
 

If you plan to keep the gateway within a private network behind a firewall, we recommend using STUN 
Server. The following three (3) settings are useful in the STUN Server scenario: 

1.  STUN Server (under Advanced Settings webpage) 

Enter a STUN Server IP (or FQDN) that you may have, or look up a free public STUN Server on the 
internet and enter it on this field. If using Public IP, keep this field blank. 

2.  Use Random Ports (under Advanced Settings webpage) 

This is a tricky setting. It really depends on your network settings, so set this parameter to Yes or No, 
whichever works.  If using a Public IP address, set this parameter to No. 

3.  NAT Traversal (under the Profile web pages) 

Set this to Yes when gateway is behind firewall on a private network.
