Try this irule as part of a Universal persistence profile. I use it when I have a similar situation to make the persistence based on both the source address and source port of the request.

when CLIENT_ACCEPTED { 
    set client_ip_port "[IP::client_addr]:[TCP::client_port]"
    persist uie $client_ip_port
}
when SERVER_CONNECTED {
    persist add uie $client_ip_port 3600
}
