ACE with servers in different datacenters

[legroseasy]

Hi all,

I have a customer who would like to load-balance between two servers which are each located in different data-centers.  I red about the source NAT but I just want to confirm if it's the way to go.  The two servers will be on different vlan.  We will be using GSS for applications which uses a domain name but he has some applications that only use IP addresses.

Thanks for your help

Hi Martin,

The problem with setups in which the real servers are not directly connected to the ACE is that, it's not trivial to ensure that the return traffic from the serves towards the clients goes back through the ACE. Source-nat is one of the ways to achieve this, and probably the easiest one, but there are other alternatives.

It is also possible to route the traffic until one hop away from the ACE and then apply policy-based-routing to send this return traffic to the ACE

Regards
