Does anyone have a simple example of a Cisco ACE (6500 blade or 4710) configuration for one-armed load balancing with SNAT? I have a load balancer in one data center that I want to LB for servers/services in another.
I found the following article: Source NAT on Cisco ACE, but this is a little more complicated than my situation.
- ACE: 10.1.1.1 & ACE VIP: 10.1.1.2
- Server1: 10.2.1.1 & Server2: 10.2.1.2
- Client: 10.3.1.1
Client goes to 10.1.1.2, gets SNAT'd as 10.1.1.1 and the request then load-balanced to Servers 1 & 2. The servers replies would then return to the ACE before being forwarded to the client.
I realize this could result, at times, in inefficient routing so if there are better ways of doing this I would appreciate any suggestions.
