It looks like you actually may be using SNAT automap, according to your confirg. The following virtual server points to the iRule above that issues a SNAT automap address based on a class match on all_server_nodes:

 

 

virtual ns-phx.bmc.com {

 

pool ns-phx.bmc.com

 

destination 172.24.4.252:domain

 

ip protocol udp

 

vlans PRDSRV200

 

PRDVIP100 enable

 

rules ns-phx-snat-iRule1

 

persist source_addr

 

}

 

 

If you create a snat pool and point this rule to that pool, it may help.
