***Static routes**: Configure static routes, if necessary. Configure static routes for Network Virtual Appliances (if applicable). Virtual WAN supports a single next hop IP for static route in a virtual network connection. For example, if you have a separate virtual appliance for ingress and egress traffic flows, it would be best to have the virtual appliances in separate VNets and attach the VNets to the virtual hub.

***Bypass Next Hop IP for workloads within this VNet**: This setting lets you deploy NVAs and other workloads into the same VNet without forcing all the traffic through the NVA. This setting can only be configured when you're configuring a new connection. If you want to use this setting for a connection you've already created, delete the connection, then add a new connection. See [bypass next hop IP documentation](../articles/virtual-wan/howto-connect-vnet-hub.md#bypassexplained) for more information about routing behavior related to this setting.

Traffic destined for addresses in the virtual network directly connected to the virtual hub can't be configured to route through the NVA using BGP peering between the hub and NVA. This is because the virtual hub automatically learns about system routes associated with addresses in the spoke virtual network when the spoke virtual network connection is created. These automatically learned system routes are preferred over routes learned by the hub through BGP.

The bypass next hop IP setting **does not apply**to routes learnt via BGP peering from a NVA deployed in a Virtual Network directly connected to the Virtual Hub. This is because the virtual hub automatically learns about system routes associated with addresses in the spoke virtual network when the spoke virtual network connection is created. These automatically learned system routes are preferred over routes learned by the hub through BGP. The system routes can only be overriden by static routes.

***Propagate static route**: This setting lets you propagate static routes defined in the **Static routes** section to route tables specified in **Propagate to Route Tables**. Additionally, routes will be propagated to route tables that have labels specified as **Propagate to labels**. These routes can be propagated inter-hub, except for the default route 0/0.
