Configuring Static Default Gateways

Static default gateways are required for all deployments implementing Internet based WAN Wide Area Network. WAN is a telecommunications network or computer network that extends over a large geographical distance. services. The default gateway is statically defined on VPNCs and dynamically derived on the Branch Gateways from the Internet Service Provider (ISP Internet Service Provider. An ISP is an organization that provides services for accessing and using the Internet.) through DHCP Dynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network.  or PPPoE Point-to-Point Protocol over Ethernet. PPPoE is a method of connecting to the Internet, typically used with DSL services, where the client connects to the DSL modem.. A static default gateway is also required on Branch Gateways connecting to an MPLS Multiprotocol Label Switching. The MPLS protocol speeds up and shapes network traffic flows. WAN or private WAN services.

HPE Aruba Networking recommends that you configure static default gateways at the device level, because default gateways are typically unique to each Branch Gateway. However, if the devices in a deployment share a common gateway, you can configure default gateways at the group level.

To configure default gateways for routing, complete the following steps:

  1. In the WebUI, perform one of the following:

    • To select a gateway group:

      1. In the Classic Central app, set the filter to a group that contains at least one Branch Gateway.

        The dashboard context for a group is displayed.

      2. Under Manage, click Devices > Gateways.

        A list of gateways is displayed in the List view.

      3. Click Config.

        The configuration page is displayed for the selected group.

    • To select a gateway:

      1. In the Classic Central app, set the filter to Global or a group that contains at least one Branch Gateway.

      2. Under Manage, click Devices > Gateways.

        A list of gateways is displayed in the List view.

      3. Click a gateway under Device Name.

        The dashboard context for the gateway is displayed.

      4. Under Manage, click Device.

        The gateway device configuration page is displayed.

  2. If you are in the Basic Mode, click Advanced Mode to access the advanced configuration options.
  3. Click Routing > IP Routes.
  4. Under Static Default Gateway, click + to add a new default gateway.
  5. Select Ipv4 from the IP version drop-down list.
  6. To use a default gateway IP, select the Default Gateway IP option and enter the default gateway IP address.
  7. To use an IPsec Internet Protocol security. IPsec is a protocol suite for secure IP communications that authenticates and encrypts each IP packet in a communication session. map, select the IPsec Map option and select the IPsec map.
  8. In the Uplink field, click the edit icon to open the Available/Selected Uplinks window to add or remove available uplinks.
  9. Enter a value for Cost.
  10. Click Save Settings.
