Million Dollar SNAT question

You can create datagroups in the GUI under Local Traffic >> iRules. Click on the datagroups tab to the right of the iRules tab, and create a datagroup of IP addresses.

 

 

If you do use the rule:

 

 

You probably don't want to use the forward command, unless you are using an IP forwarding VIP. If you just remove the "else { forward }" portion of the rule, the request will be processed according to the VIP configuration and be directed to the pool.

 

 

As far as the SNAT option:

 

 

What I was trying to suggest is that you could use SNATs to create a mapping of source IP addresses to translation IP addresses for each node. If a request from one of the nodes is received, the BIG-IP will translate the source IP address from the node IP to the translation IP defined in the SNAT.

 

 

Either the rule or the configured SNAT option should work with the same result.
