Hi All,
We are trying to configure client NAT on ACE , I have tried with the following configuration.
I want to make sure the following things
1) Whether this is a right way or not or if this is possible?
2) If it is and any one is having ideas for that please do let me know so that I can send the topology diagram as well to get it understand easily.
class-map match-all CLIENT-TO-AVS-VIP
2 match virtual-address 172.16.30.110 tcp eq www
class-map match-all NAT
2 match source-address 0.0.0.0 0.0.0.0
3 match destination-address 172.16.30.110 255.255.255.255
policy-map multi-match MOON-POLICY
class CLIENT-TO-AVS-VIP
loadbalance vip inservice
loadbalance policy MOON_AVS_CLIENT
loadbalance vip icmp-reply
class NAT
nat dynamic 9 vlan 300
interface vlan 300
description Clentside interface
bridge-group 30
access-group input ALL
nat-pool 9 172.16.30.200 172.16.30.210 netmask 255.255.255.255 pat
service-policy input REMOTE-MGMT
service-policy input MOON-POLICY
no shutdown

Here is a good article on doing that.

Hi Aslam,
yes it's possible in a quite simple way, I see some errors in your configuration :
You don't need a second class map "NAT", the first one is sufficient. You can tell the ACE "When traffic matches CLIENT-TO-AVS-VIP, loadbalance AND nat client traffic".
To do so, simply insert the "nat dynamic 9 vlan 300" command inside the "class CLIENT-TO-AVS-VIP" mapping in the multi-match policy.
This should work as you want :
class-map match-all CLIENT-TO-AVS-VIP
2 match virtual-address 172.16.30.110 tcp eq www
policy-map multi-match MOON-POLICY
class CLIENT-TO-AVS-VIP
loadbalance vip inservice
loadbalance policy MOON_AVS_CLIENT
loadbalance vip icmp-reply
nat dynamic 9 vlan 300
remember that an instruction like
"2 match source-address 0.0.0.0 0.0.0.0" is a pleonasm, no instruction on source-address means match any source.
You can check some other scenarios on source nat here :

Hope this helps.
