Use iRule to SNAT based on Destination IP address without using a SNAT Pool.

I've seen an answer for a similar question on here, but the solution was to use a SNAT pool. Here's my situation:

 

• ServerA that needs to reach out to an external IP address.
• ServerA is in a SNAT pool already with two other servers.
• The other two servers cannot have access to this external IP address
• ServerA cannot be added to a second SNAT pool.

So what I was hoping to do was to be able to write an iRule (or preferably apply a Local Traffic Policy) that would SNAT traffic from ServerA to a specific IP address when it is going to this particular external IP address.

 

Any suggestions?

 

Thanks.
