iRules for SNAT translations with ISP load balancing
I'm looking for a way to create iRules that would have SNAT translations for specific hosts that needed to be sourced with a specific IP address and autosnat all others. For example, Node A must be sourced from public IP 100.1.1.2 using ISP A, node B would be sourced from public IP 200.1.1.3 using ISP B, while all others that did not need to be sourced from a specific IP would use autosnat to load balancing using both ISPs and setting the source IP to the appropriate self-IP based on the ISP connection used. Is this possible and if so what would the iRule look like?
