Subnets and Virtual DNAT Networks on the MergePoint 5224/5240 SP Manager on page 50 and in
more detail in Target Device Configuration on page 169.
At least one subnet is needed to enable devices that are connected to the SP manager’s private
Ethernet ports to communicate on the Internet via the SP manager’s public IP address. Any number
of private subnets may be configured. Configuration of one or more virtual networks is optional.
Subnets are defined using the values described in Table 4.17 on page 51.
Virtual networks are defined using the values described in Table 4.18 on page 52.
CAUTION: Changing or deleting an existing private subnet changes the configuration of any device that was
previously configured to use that private subnet; the private subnet is removed from the device’s configuration,
and on subsequent attempts to contact the device, the SP manager tries to use the default route. If changing or
deleting a private subnet, make sure to reassign all affected devices to another private subnet to avoid making
devices unavailable.
