ISP Load Balancing and SNAT iRules

I'm looking for a way to load balance routing to multiple ISPs by using autosnat for the bulk of the traffic and specific SNATs for specific applications. It appears that by default autosnat overrides any defined SNATs. Is there a way to define specific iRules and/or virtual servers to use the defined SNATs per VLAN interface for specific applications and autosnat for the remainder?

    Hi anything that you define in irule will take precedence to your config. So in your case you can define a snat pool containing both ISP IP for your outband virtual. Then you use irule to match application and select another snat pool or specific ip.
