ARP

Determines the VSU use of its MAC addresses. In the default mode (Bind one IP address to
each port), the Primary IP address is bound to the MAC address of the public port. If a private IP
address is configured, that address is bound to the MAC address of the private port of the VSU.
In this mode, all packets originating from the VSU destined for the public network uses the
public port's MAC address as the packets' source MAC address.
Examples of public network destined traffic are:
IPSec packets being tunneled to a member VSU
SNMP Get Responses being sent to a VPNmanager console residing on the public side of
the VSU
Traps sent to a VPNmanager console residing on the public side of the VSU
Also in the default mode, all packets originating from the VSU destined for the private network
use the private port's MAC address as the packets' source address.
