IOS-XE - NAT 'tcp load balancing' (using "ip nat inside destination list pool") is not supported?

[Dmitri Olchevski]

trying to configure this on an Azure CSR instance running ios-xe 16.10.1b, and it acts weird:

it accepts "ip nat inside destination list <number>", but there's no "pool" option after it:

(config)#ip nat inside destination list 50 ?
redundancy NAT redundancy operation
<cr> <cr>

trying to configure a typical NAT 'load balance' scenario, as per the example below:

interface Ethernet0
ip address 192.168.1.1 255.255.255.0
ip nat inside
!
interface Serial0
ip address 207.35.14.82 255.255.255.252
ip nat outside
!
ip nat pool V-Server 192.168.1.2 192.168.1.4 prefix-length 24 type rotary
ip nat inside destination list 1 pool V-Server
!
ip route 0.0.0.0 0.0.0.0 Serial0
!    
access-list 1 permit 199.198.5.1
!

Hello,

I am running the AX (Application Experience) feature set, maybe that is the problem...which one are you running (sh lic) ?

[Dmitri Olchevski]

Hello,

maybe AWS, for some reason, has disabled that command ? Always worth checking maybe...
