There are many ways to do that, I will give a couple ones.

 

First option, multiple virtual servers.

 

You could create multiple forward virtual servers with destination 0.0.0.0/0 and source as the server ip, and with the snap pool with the IP you want.

 

Second, single forward virtual server, and irule + datagroup. The iRule would perform the snat based in the source IP and get the snat IP from the datagroup.
