IP Masquerading (IP “Spoofing”)
  When IP Masquerading is enabled, unsolicited outside messages are blocked from entering the LAN. The originating
addresses of inbound messages are checked to verify that they come from legitimate addresses. Enabling IP Masquerading
blocks messages originating at these addresses:

•  Local LAN addresses

•  IP address of 0.0.0.0

•  Private IP addresses:

– Any address beginning with “192.168.” (192.168.*.*)
– Any address in the series 172.16.*.* through 172.31.*.*
– Any address beginning with “10.” (10.*.*.*)

To enable or disable IP Masquerading:
1.  Click the Enable option button to allow IP Masquerading. Click the Disable option button to prevent IP Masquerading.
2.  Click the Save button at the bottom of the Advanced Access screen when finished. WebShare will prompt for a restart.
