Click here for previous post to see the lab setup.
Here is a basic Alteon setup with very basic server loadbalancing.
The VIP is 10.136.85.10 and the Source NAT, or proxy ip in Alteon terminology is 10.136.85.200. We need the SNAT, as otherwise the Alteon will reply directly to the client. We need the reply traffic to pass through the Alteon to get it translated back to VIP from the real IP address of the selected server.
Notice that that we have a default GW for the management interface, and a different gateway for the data path, which is the traffic from the client and to the servers.
