IP NAT redundancy

DRAFT: BROCADE CONFIDENTIAL

ServerIronADX(config)# access-list 10 permit 10.1.1.0 0.0.0.255

4. Configure a dynamic NAT pool on each ServerIron ADX, and assign device ownership to the NAT

pool. In this example, ServerIron ADX A is assigned as the NAT Pool owner, and therefore takes

the higher priority value:

SI_A(config)# ip nat pool P1 63.2.63.200 63.2.63.200 prefix-len 24

SI_A(config)# ip nat pool P1 port-pool-range 2

SI_B(config)# ip nat pool P1 63.2.63.200 63.2.63.200 prefix-len 24

SI_B(config)# ip nat pool P1 port-pool-range 1

5. Tie the inside source ACL to the dynamic NAT pool and enable PAT (overload)

ServerIronADX(config)# ip nat inside source list 10 pool P1 overload

ServerIronADX(config)# ip nat inside

6. Configure the inside interface of the default gateway router with an IP address from both the

dynamic NAT pool subnet, as well as the inside network. The reason is that the default gateway

should be ping-able from both the ServerIron ADX switch as well as from the private client

subnet. For example:

Router(config)# interface ve 2

Router(config-VE)# ip address 63.2.63.44 255.255.255.0

Router(config-VE)# ip address 10.1.1.1 255.255.255.0

Configuring static NAT redundancy in Hot-Standby mode

Follow these steps to enable the minimum required configuration for static NAT in Hot-Standby

mode, as shown inFigure 23.
