The topology above is about how the branch office can get the access to the headquarter server. The two laptops are
connected to the device using the Ethernet cable.
The laptop at the branch office picks a role as the VPN Client and the laptop at headquarter picks a role as the VPN
Server. To get the access to the server the branch office need to connect to the VPN Server. As we can see the
connection is established through the LTE connection. In this case, IPsec connection needs to be enabled. See the
setting below.
When the connection is enabled, then the IPsec status will directly change to connected status, which means that
the connection is established. So that the laptop at the branch office can access the server at headquarter.
