Hello. I am running a smtp virtual service on one subnett and two exchange 2013 real servers on another subnett. The external SMTP relay connectors on the real servers are working when connecting directly to the servers, but not through the virtual service. When i try to enable transparancy it does not seem like the servers are able to answer the smtp request. Am I suppose to use DSR in this scenario? We are using kemp loadmaster 2200 with firmware Vers:7.1-16.
