Use Specific Gateway Pool based on SNAT address

Hi All,

 

Currently we have 3 ISP Links which I am trying to get routing correctly based on outbound SNAT. I have created SNAT Pools for the internal subnets that contain a IPs from each of the three ISPs. The F5 seems to be SNATing to one of the external IP's from the pool then using our Wildcard Server, Round Robin to send the traffic down any one of the three ISP links. This results in the traffic going down the right link only every other time.

 

ISP A

 

ISP B

 

ISP C

 

Internal 192.168.20.0/24

 

Current Issue

F5 -> Snat addresses 192.168.20.0/24 to external IP from ISP A -> Round Robin and send down link ISP A, B or C

 

I would like to configure it so the F5 uses the correct ISP link based on its SNAT address. Someone please tell me this is possible?

 

Best Regards, Scott
