Citrix and APM Dynamic Webtop NAT Options

If the SNAT option is set to 'None' you will see the real client IP address. The caveat here is that the servers must then use the BigIP as the default gateway otherwise you will end up with an asymmetric route back to the client. With SNAT enabled the servers will see on of the SNAT pool IP's as the source. With automap the servers will see the floating self IP and if no floating self IP exists it will be the Self IP of the active BigIP.
