I have configured a Virtual Kemp (Version 184.108.40.206.14750.RELEASE) on VMWARE.
Two NICS are enabled, eth0 for management and eth1 for Exchange. VLANS are sorted on VMWARE and are not configured on the Kemp.
The default gateway is configured on eth0 for the Kemp, however each virtual service has its gateway configured to use the Exchange network default gateway.
I have configured an SMTP virtual service on the kemp checking on port 25. This monitors the SMTP service on an Exchange 2013 server.
I have configured the Exchange 2013 receive front end connector so that it only accepts traffic from the virtual service IP defined above.
The real server checks on the Kemp state that the service is down. When I change the receive connector to allow all IP's the service changes to up on the Kemp.
I have performed a wireshark and it appears that the Health check for the SMTP service is coming from the IP address of the interface connected to the exchange network and not from the Virtual Service IP. Subnet Originating Requests is not enabled.
In fact the Wireshark trace indicates that health checks to all virtual services on the Kemp are being done through the Kemp Interface IP on the Exchange network and not the virtual server.
Note the other Virtual services I have created for Exchange 2013 all appear to work ok, just not the SMTP virtual service.
Any Help would be appreciated.
