Default Re: Could someone explain/help. NAT query for VRRP setup.

No, when configuring VRRP on a Nokia you need,

1 physical IP address per Node, total of 2, 1 for each box. This is configured on the box itself. This is used to manage the individual boxes.
1 virtual VRRP address that is shared and is used for routing etc.

This uses a total of 3 addresses per interface.

For your proxy arp's ie for SMTP Mail Server NAT then you just define a single IP address and configure so that the Nokia will proxy arp with the VRRP MAC Address. This should not be your VRRP address but a unique IP address in your public IP range.

By using the VRRP MAC then only the master unit will respond to traffic to that MAC address. Also if you have a failover then the same MAC address is used if the secondary box becomes active.
