Abstract:
The method of some embodiments synchronizes NAT records between an active gateway and a standby gateway. The active gateway encodes a NAT record that includes at least an external source IP address. The encoded NAT record does not include the external source IP address but does include an identifier that uniquely specifies the external source IP address. The active gateway sends the encoded NAT record to the standby gateway.
