iRule to Decrypt and then Re-Encrypt outbound traffic

The problem here is that the destination is always changing. The server processes outbound traffic for a number of different systems out on the Internet. This is why I was looking for an iRule that I can apply to the router, as I know they can process iRules. I also know that iRules can apply certs to outbound packets via SNAT, which according to my understanding is useful when you are dealing with a limited known set of destinations. In this case, we just need to apply a rule to a port based off of a known source address, this being the server.
