In essence, two TCP instruments are correcting a single packet of IP data, undermining network throughput and causing connection timeouts. When packet loss occurs (which happens even under optimal internet conditions), a performance degradation effect called TCP-over-TCP meltdown occurs. This results in application layer data being encapsulated twice in two separate TCP streams. Conventional full-access SSL VPNs tunnel sends TCP/IP data in a second TCP/IP stack for encryption over the internet.If you selected Send traffic over the tunnel, select Enable TCP Optimization to optimize the internet speed.Specify whether you want to send private network and internet traffic over the SSL VPN-Plus enabled NSX Edge or directly to the private server by bypassing the NSX Edge.Type the netmask of the private network.On the Private Networks Menu Add the network that you want the remote user to be able to access. The IP Pool should be on a different Subnet to the configured VNICs The remote user is assigned a virtual IP address from the IP pool that you create. Head to the IP Pool Menu and add an IP Pool.
Note that if you are going to be hosting SSL Enabled services off the Edge it’s probably a good idea to use a non standard HTTP Port such as 9443 so as not to have issue binding web services later on. Select the Primary IPv4 Address and choose the SSL Certificate (for the purpose of this example the default should be ok) and click ok. To enable the SSL VPN you need to go to Networking & Security -> NSX Edges, double click on the edge in question and go to the SSL VPN-Plus Tab and then go to Server Settings and click on Change The steps to configure and enable the SSL VPN are listed below with each step expanded out through the rest of the post.

#VPN PLUS AND 443 WINDOWS#
Windows is used in the example above but there are also clients for MacOS (Tiger, Leopard, Snow Leopard, Lion, Mountain Lion, and Maverick) or Linux (TCL-TK is required for UI to work. The graphic above is pulled from the NSX Online Documentation and shows the basic logical overview of what the SSL VPN-Plus feature enables.
With the SSL VPN-PLUS remote users can connect securely to private networks behind VSE and NSX Edges allowing remote users to access servers and applications in the private networks or Virtual Datacenters. Contributing to it’s lack of use was the fact that the functionality was not exposed via vCloud Director so one of the best use cases for the SSL VPN remained hidden to those that might have taken advantage of it the most. The SSL VPN-Plus feature has been around since the VSE 5.x days and as I’ve found out was possibly the best underused feature of the VSE.
