Hello!
We have finally replaced the old Cisco 2851 on the more recent Cisco 4331. The config from the old 2851 was successful moved to 4331 except for one moment. Rotary nat was used to load balance external connections to internal mail servers on 2851, but it didn't work on the new 4331.
Ambiguous command: "ip nat inside destination list 100 pool pool-mail"
This is nat related config from Cisco 2851:
ip nat pool pool-mail 10.10.10.11 10.10.10.12 netmask 255.255.255.0 type rotary
ip nat inside source list acl-nat interface GigabitEthernet0/0 overload
ip nat inside destination list 100 pool-mail
access-list 100 permit tcp any host 100.100.100.100 eq www
access-list 100 permit tcp any host 100.100.100.100 eq 443
access-list 100 permit tcp any host 100.100.100.100 eq smtp
This from Cisco 4331:
ip nat pool pool-mail 10.10.10.11 10.10.10.12 netmask 255.255.255.0 type rotary
ip nat inside source list acl-nat interface GigabitEthernet0/0/0 overload
ip access-list extended 100
permit tcp any host 100.100.100.100 eq www
permit tcp any host 100.100.100.100 eq 443
permit tcp any host 100.100.100.100 eq smtp
When I try setup nat destination, I see this "Ambiguous command: "ip nat inside destination list 100 pool pool-mail"
I read docs
But example did't work:
ip nat pool real-hosts 192.168.15.2 192.168.15.15 prefix-length 28 type rotary
access-list 2 permit 192.168.15.1
ip nat inside destination list 2 pool real-hosts
interface gigabitethernet 0/0/0
ip address 192.168.15.129 255.255.255.240
ip nat inside
interface serial 0
ip address 192.168.15.17 255.255.255.240
ip nat outside

rt-01(config)#ip nat inside destination list 2 pool real-hosts
% Ambiguous command: "ip nat inside destination list 2 pool real-hosts"
I have Cisco ISR 4331 HSECK9 Version 16.9.7 Fuji
Community, please help.
