Sticky IP addresses

The vRGW can be programmed with a list of sticky IP addresses per BRG. A sticky IP address is an IPv4 address from the home pool allocation range that is set aside for a specific device based on the MAC address and is never allocated to any other device. This can be used for devices where a persistent IP address is desirable but configuring a static IP address on the device is too cumbersome (such as a network printer). The device still uses DHCP to gain connectivity but is always assigned the same IP address.Public (non-NAT) sticky IP addresses are not directly supported in pool management but can be provisioned in the following manner.

  1. Create a local DHCP server and pool to manage the public address space.

  2. For each public sticky IP address that must be provisioned, create a sticky lease in this pool. See DHCP Address Reservation for Sticky Leases for further details. Both the user identification and hostname can be the MAC address of the associated device.

  3. When the device linked to the sticky lease authorizes with the controller, it returns the allocated address as a framed IP address. This address takes precedence over any home pool configuration and a DHCP proxy host is installed.
