Any one confirm please , below irule will give me this solution?

SNAT for outbound connections from members to internet and intranet members IP range: 172.0.0.0 single vip with IP 192.0.0.5

So members can access the internet via same vip to internet and intranet? Actually i dont understand how this taking applying for only outbound connections?

{ when CLIENT_ACCEPTED {

     if { [IP::addr [IP::client_addr] equals 172.0.0.0] }
      { snatpool xxxx }
      elseif 
       { snat none } 
    }
}
