The L2 VPN server is the destination NSX edge to which the L2 VPN client is going to connect.
About this task
As described in the NSX Administration Guide, you can connect multiple peer sites to this L2 VPN server.
Changing site configuration settings causes the edge gateway to disconnect and reconnect all existing connections.
You must have the server's listener IP, listener port, encryption algorithm, and at least one peer site configured before you can enable the L2 VPN service.
Verify the edge gateway has a routed organization virtual datacenter network that is configured as a subinterface on the edge gateway. See the vCloud Director Administrator's Guide for the steps on creating an external routed organization virtual datacenter network.
Verify you have completed the steps described in Navigate to the L2 VPN Screen in the Tenant Portal.
If you want to bind a service certificate to the L2 VPN connection, verify that the server certificate has already been uploaded to the edge gateway. See Add a Service Certificate to the Edge Gateway.
- On the tenant portal's L2 VPN tab, select Server for the L2 VPN mode.
- Click the Server Global tab if it is not already selected.
- Configure the L2 VPN server's global configuration details.
Type the primary or secondary IP address of an external interface of the edge gateway.
The default port for the L2 VPN service is 443. Edit the displayed value as appropriate for your organization's needs.
Select the encryption algorithm for the communication between the server and the client.
