DTGW: a transit gateway that bypasses Edge-node Tier-0s, with hosts connecting out over their own VLAN. Routing, external IPs and DHCP are distributed, but NAT, DHCP relay and similar stateful features cannot be used.
Also called DTGW.

Terms in this definition
- transit gateway
Joins up a project's VPCs with each other and with outside networks in NSX, either in a distributed fashion on the hosts or centrally via a Tier-0 gateway running on an Edge cluster.
- OVER
Gives a T-SQL window function its window: PARTITION BY, ORDER BY and, if wanted, a ROWS or RANGE frame. Rankings and running totals can then be worked out while every row is kept.
- VLAN
Layer 2 broadcast domain tagged using 802.1Q. In VCF they carry TEP, vSAN, vMotion and management traffic, and NSX can back segments with them.
- Geographic
A Traffic Manager routing method that picks the endpoint according to where the user is located geographically.
- External
API Management virtual network mode in which the gateway stays public but can call private back ends inside the VNet.
- DHCP
Azure delivers each NIC's private IP to the guest operating system using this protocol, so keep the OS set to obtain addresses automatically and configure any static IP on the Azure NIC.
- Azure NAT Gateway
Gives every resource in a subnet a managed way out to the internet through one or more fixed public IP addresses, while accepting no unsolicited inbound connections. Azure Container Apps can use it only when the environment is a workload profiles one.
- Document Intelligence add-on capabilities
Extra Document Intelligence options switched on with the features query parameter: barcodes, formulas, keyValuePairs, languages, ocrHighResolution, queryFields and styleFont.

- Centralized transit gateway
With its connection type set to centralised, an NSX transit gateway offers one external link only; the distributed flavour (DTGW) allows more. If an active-active Tier-0 is in use, Default Outbound NAT cannot be switched on.
- VPC Getting Started
Edge-less NSX workload networking model: a distributed transit gateway and dedicated external VLAN link VPCs to the fabric, at the cost of centralised services like VPN, NAT, Auto SNAT and the gateway firewall.
