If the Video Firewall feature is enabled (see Upgrading the firmware), you will need to set up one or more routing settings
to control how IP traffic flows in and out of the IP VCR.
It is important that these settings are configured correctly, or you may be unable to make calls to or from the IP VCR or
access the web interface.
To configure the route settings, go to Network > Routes.
In this section:
• Port preferences
• IP routes configuration
• Current IP status
Port preferences
If both Ethernet ports are enabled, it is necessary to specify which port is used in certain special circumstances. Make the
appropriate selections described below, then click Apply changes to make any changes take effect.
Field Field description Usage tips
Default
gateway
preference
The IP address to which the IP VCR will send
packets in the absence of more specific routing (see
IP routes configuration). Therefore, it only makes
sense to have precisely one default gateway, even
though different default gateways may have been
configured for Ports A and B. Use this option to
decide which port's default gateway configuration
to use as the unit's default gateway.
If Ethernet Port B is disabled, you cannot specify
that port as the default gateway preference.
Selecting Port B as default gateway preference then
disabling Port B will cause the preference to revert
to Port A.
Name server
(DNS)
preference
The IP address to which the IP VCR will send
requests to look up unrecognized host names in
order to determine their corresponding IP
addresses. Only one name server (and associated
secondary name server) may be used, even though
different name servers may have been configured for
Ports A and B. Use this option to decide which
port's name server configuration to use as the unit's
name server.
If Ethernet Port B is disabled, you cannot specify
that port as the name server preference.
Selecting Port B as name server preference then
disabling Port B will cause the preference to revert
to Port A.
IP routes configuration
In this section you can control how IP packets should be directed out of the IP VCR. You should only change this
configuration if you have a good understanding of the topology of the network(s) to which the IP VCR is connected.
Configuration of routes is divided into two sections: addition of new routes, and the display and removal of existing
routes.
