NAT46 static mapping configuration

DRAFT: BROCADE CONFIDENTIAL
5. The IPv6 client replies using the synthesized IP address (2001:db8:64::192.0.2.1) as the DIP
and its own IPv6 address (2001:db8:80::80) as the SIP.
6. The NAT46 gateway strips out the IPv6 portion of the DIP (that is, the IPv6 prefix) and uses the
remaining IPv4 portion (192.0.2.1) as the destination address.
7. The NAT46 gateway uses the mapping table to map the IPv6 SIP (2001:db8:80::80) to the IPv4
address that represents the resource to the IPv4 network (200.1.1.1). This is the same
address that the DNS server uses for brocadetest.com.
The process occurs as shown in Figure 14.
FIGURE 14 Stateless NAT46 translation
Populating the NAT46 mapping table
The stateless NAT46 gateway uses a mapping table to translate the IPv4 destination address that
the IPv4 network uses to identify the IPv6 resource into the actual IPv6 address of that resource.
This mapping table can be configured manually (using static mapping) or generated dynamically
(using real-time dynamic learning or prefetched dynamic learning). A maximum of 1024 entries is
supported in the mapping table.
In configurations using static mapping, all entries in the NAT46 gateway mapping table are
manually defined using the nat64 map command.
Dynamically generated mapping tables can be populated in real time by way of real-time dynamic
learning or pre-populated by way of prefetched dynamic learning. You must configure a DNS server
IP address on the ServerIron ADX to use dynamic mapping.
NAT46 static mapping configuration
In NAT46 configurations using static mapping, the mapping table used to match IPv4 and IPv6
addresses is populated manually using the nat64 map command.
