Terms in this definition
- Virtual WAN
A networking service built around hubs that Microsoft manages. The Basic type handles only site-to-site VPN; Standard brings in ExpressRoute, point-to-site and full transit.
- Virtual hub
Inside a Virtual WAN, a VNet managed by Microsoft that contains the hub router plus the VPN, ExpressRoute and User VPN gateways. Typically there is one per region, but several hubs can share a region.
- Route table
Resource containing user-defined routes and attached to subnets, shaping traffic that leaves them. Attaching one to GatewaySubnet steers traffic coming in over VPN.
- Connection
Resource that attaches a virtual network gateway to its peer, which may be an ExpressRoute circuit, a second VNet gateway (Vnet2Vnet) or a local network gateway over IPsec. Resetting it recovers a single tunnel and avoids rebooting the whole gateway.
