The tier-0 gateway is the NSX logical router that provides the North-South connectivity for the NSX logical networking to the physical infrastructure. vSphere with Tanzu supports multiple tier-0 gateways on multiple NSX Edge clusters in the same transport zone.
You can configure the HA (high availability) mode of a tier-0 gateway to be active-active or active-standby. The following services are only supported in active-standby mode:
- NAT
- Load balancing
- Stateful firewall
- VPN
Before NSX 3.2, proxy ARP is supported on a tier-0 gateway in only an active-standby configuration. Starting in NSX 3.2, proxy ARP is also supported on a tier-0 gateway in an active-active configuration.
For more information, see the NSX Administration Guide.
