NSX edge supports site to site IPSec VPN to remote sites. You can configure multiple internal networks to connect to through the VPN tunnel. Subnets and internal networks behind the NSX edge must not have overlapping addresses. The size of the edge device determines the number of tunnels that are supported. The number of tunnels needed can be found out by using a simple equation of : “local subnets x peer subnets = number of tunnels needed”. Below is a chart taken from the NSX Administrator’s Guide outlining the number of IPSec tunnels that a edge device can handle depending on the size and also the supported algorithms.

One of the services that the NSX Edge (ESG) provides is IP address pooling and one-to-one static IP address allocation and external DNS services. NSX Edge listens to the internal interface for DHCP requests and uses the internal interface IP as the default gateway for clients. In this post, I’ll show you how to configure DCHP on the NSX Edge to provide IP addresses to clients on a logical switch.

First, navigate to Networking & Security > NSX Edges and select you ESG. Then navigate to Manage > DHCP > Pools. Under Pools, click the green “+”.
