We have a one armed CSS configuration that needs to do source NAT for simple Content Rule to backend server balancing.
So we have configured services, included those services in a content rule and configured a group with the services as destination services.
This works fine until we want to add a new service. When we add the service to the content rule, it also needs to be added to a group. However, to add a destination service to a group you have to suspend the group (also for the remove). We think this leads to potential disruption of service. Is that correct?
So would a better way be to configure the group with a VIP but no destination services and rely on an acl clause to "permit" traffic to the content rule with the source group specified?
Am I right in thinking I can now add and remove services from the rule without having to do anything else and therefore preserve connectivity for all existing connections?
What are the likely pitfalls, if any?
