load balancing based on source IP address

gpangallo · ‎04-07-2008

Hi,

I configured a CSS to balance the load depending on source IP address to suppport a application feature in the server.

We have two firewalls and behind we have different users. We have also two servers behind the CSS.

Firewalls perform NAT with a unique outside IP address. So, for example, in these conditions the CSS balances requests coming from FW 1 to server 1 and requests coming from FW 2 to server 2. Is it correct this scenario?

Is it possible that requests coming from FW 1 could be forwarded to Server 2 and viceversa?

Could anyone answer me?

Thanks in advance.

Best regards.

Giuseppe.

Giuseppe,

it all depends on how you configured your CSS.

Did you use an ACL to force traffic from SRC1 to server1 and traffic from SRC2 to server2 ?

Or did you simply configure sticky based on source ip or a source ip hash loadbalancing ?

Except the ACL, all other methods do not guarantee that the traffic will be splitted in 2.
