About local network detection
Note: This option is not currently available in Windows 8.
You can assign the local network for this computer to firewall rules.
The firewall determines this computer's local network when it starts, and then monitors for any changes whilst it is running. If any change is detected, the firewall updates any local network rules with the new local network address range.
CAUTION: We strongly advise caution when using local network
rules as part of configurations that may be used in "out of office" locations.

Create a secondary configuration.
