ace module in bridged mode with client nat

Could someone confirm whatever a NAT is supported for ACE-20 module, please?

Let me to explain technical details.

I do need to convert working CSM(SLB) config to ACE configuration and I am not quite sure

if the configuration below is correct. ACE module should be configured in bridge mode with two

vlans - vlan 36 (client) and vlan 436 (server) - bridged with interface bvi 36.

NAT on ACE configurad as "nat dynamic 1025 vlan 436" into corresponding

"policy-map type loadbalance"

Could you check two parts of configs and advise me if the ACE config is

properly converted from CSM and will be working in the same way (especialy for NAT).

Thank you in advance.

ace module in bridged mode with client nat

Hello F.Makarenko-

  You will want to use PAT while you do nat, so change the natpool configuration to this:

   nat-pool 1025 10.36.3.100 10.36.3.100 netmask 255.255.255.0 pat

  You also need to apply the nat like this:

policy-map multi-match IFVLAN36-POLICY

class WEBMAIL-80

    appl-parameter http advanced-options HTTP_ADV_OPT

    loadbalance policy WEBMAIL-80

    loadbalance vip inservice

    loadbalance vip icmp-reply active

    nat dynamic 1025 vlan 436

  class WEBMAIL-443

    appl-parameter http advanced-options HTTP_ADV_OPT

    loadbalance policy WEBMAIL-443

    loadbalance vip inservice

    loadbalance vip icmp-reply active

    nat dynamic 1025 vlan 436

If you are going to build out a lot of classes, you can instead do source nat like this:

policy-map multi-match IFVLAN36-POLICY

class WEBMAIL-80

    appl-parameter http advanced-options HTTP_ADV_OPT

    loadbalance policy WEBMAIL-80

    loadbalance vip inservice

    loadbalance vip icmp-reply active

class WEBMAIL-443

    appl-parameter http advanced-options HTTP_ADV_OPT

    loadbalance policy WEBMAIL-443

    loadbalance vip inservice

    loadbalance vip icmp-reply active

class class-default

    nat dynamic 1025 vlan 436

Chris Higgins

Hello Chris,

Thank you for your suggestion regarding source nat, I will try to implement it.
