CPE NAT IP hooks

CPE NAT IP hooks are run with the “start” argument after a CPE NAT IP is added and with the “stop” argument before it is removed.

After a CPE NAT IP hook has been added, you must restart the bond from the management server or from the host command line to execute the hook the first time.

Hook locations:

  • /etc/bonding/cpenatip.d/all: hooks to be run for all CPE NAT IP

  • /etc/bonding/cpenatip.d/<CPE NAT IP ID>: hooks for individual CPE NAT IPs

  • /etc/bonding/cpenatip.d/default: hooks for CPE NAT IPs with no individual hook folder

An example CPE NAT IP hook is available at /usr/share/doc/bonding/examples/cpenatip-hook.

Environment variables

CPE NAT IP hooks are run with the following environment variables:

  • ID: the CPE NAT IP ID

  • BOND_ID: the ID of the CPE NAT IP’s bond

  • IP: the IP address

  • DEST_NAT_IP: The NAT IP address

  • DEST_NAT_NETMASK: The NAT IP netmask
