Setting the router to dial a connection when traffic is detected on specific ports
In some situations, you may wish to have the internet connection disabled except at times when outbound traffic to a particular
external host's port or group of ports is sent to the router. To use this feature, click Enable dial port filter and enter the port number
or list of port numbers separated by commas. When you select this option, all outbound ICMP/TCP/UDP packets to any remote
host on the specified port(s) will trigger the connection to dial. Note that when this feature is enabled, the options to ignore specific
packet types are not available.

You can allow Microsoft network awareness (NCSI) traffic through but if you prefer that they do not trigger the connection, click the
Ignore Microsoft network awareness (NCSI) traffic toggle key to set it to ON.

Excluding certain packet types from triggering the connection to dial
Depending on your environment, you might prefer to exclude certain types of traffic passing through the router from triggering the
data connection. You can tell the router to ignore outbound TCP, UDP or ICMP packets. When any of these options are checked
the router will not dial a connection when that type of outbound destined data packet reaches the router from a locally connected
device.
Figure 26 – Connect on demand - Excluding IP protocols
Excluding certain application types from triggering the connection to dial
Some devices may generate general traffic as a part of normal operation which you may not want to trigger the data connection.
You can set the router to ignore Domain Name System (DNS), Network Time Protocol (NTP) or Microsoft network awareness (NCSI)
traffic from devices behind the router. When you check the box for these options, it tells the router to ignore the request from that
application type and will not dial a connection when this data type is received.
