IP Forwarding Virtual Server v/s SNAT

oops, sorry it should be IP::local_addr rather than IP::server_addr.

ltm data-group internal node_address {
    records {
        10.10.10.1/32 { }
        10.10.10.2/32 { }
    }
    type ip
}
ltm data-group internal campus_address {
    records {
        65.66.67.68/32 { }
    }
    type ip
}
ltm rule qux {
    when CLIENT_ACCEPTED {
  if { [class match -- [IP::client_addr] equals node_address] } {
    if { [class match -- [IP::local_addr] equals campus_address] } {
      snat none
    } else {
      snat 190.191.192.193
    }
  }
}
}
