7.3.1 NAT Settings
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 Super 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 Super Settings webpage)
It really depends on your network settings, so set this parameter to Yes or No, whichever
works. Generally if you have multiple IP devices under the same network, it should be set
to Yes. 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.
