DRAFT: BROCADE CONFIDENTIAL
Configuring NAT64 for IPv6-only client to IPv4 resource
Basic configuration of NAT64 for an IPv6-only client to an IPv4-only resource is performed using the
following:
• Configure a NAT64 IPv6 prefix (required)
• Configure an IPv4 NAT address pool (required)
• Enable the ServerIron ADX to delete sticky sessions (optional)
• Enable connection logging (optional)
Other configuration options are described later in the chapter.
NOTE
If you are configuring NAT64 on a system that has had a previous SLB configuration see “When
installing NAT64 on a ServerIron ADX with a previous config” on page 6
Configuring a NAT64 IPv6 prefix
A NAT64 IPv6 prefix is configured on a ServerIron ADX as shown.
ServerIron ADX(config) nat64 ipv6-prefix 2001:db7:8000::/96
Syntax: [no] nat64 ipv6-prefix <prefix/subnet> [inject-static-route { ve <port-number> | ethernet
<port-number> } ]
NOTE
The maximum number of NAT64 prefixes that can be configured is 8.
The <prefix/subnet> variable specifies the NAT64 IPv6 prefix that will be used by the ServerIron
ADX when operating as a NAT64 gateway.
The inject-static-route option is used to advertise the subnet defined by the <prefix/subnet>
variable to the IPv6 network. It is configured by an IPv6 interface specified by the ve
<port-number> or ethernet <port-number> variable. It should be the interface connected to the
adjacent router. This option is described in detail in “Route injection NAT64” on page 13.
Configuring an IPv4 NAT address pool
You can configure a NAT64 IPv4 NAT address pool as shown.
ServerIron ADX(config) nat64 pool nat64-zone1 201.1.1 201.1.1.20 prefix-length 24
Syntax: [no] nat64 pool <pool-name> <start-IPaddress> <end-IPaddress> prefix length <prefix
length> [ port-pool-range { 1 | 2 } ] [ inject-static-route ]
NOTE
The maximum number of IP addresses that can be configured in a NAT pool is 192.
The <pool-name> variable specifies the name of the NAT64 IPv4 pool. The name can be up to 255
characters in length.
The <start-IPaddress> variable specifies the IPv4 address at the beginning of the NAT64 pool
range. This value should be the lowest numbered IPv4 address in the range.
