Chapter 4
Configure the Network with Omada SDN Controller
There are many variations of virtual private networks, with the majority based on two main models:
Site-to-Site VPN
A Site-to-Site VPN creates a connection between two networks at different geographic locations.
Typically, headquarters set up Site-to-Site VPN with the subsidiary to provide the branch office
with access to the headquarters’ network.

Omada managed gateway supports two types of Site-to-Site VPNs:
Auto IPsec
The controller automatically creates an IPsec VPN tunnel between two sites on the same
controller. The VPN connection is bidirectional. That is, creating an Auto IPsec VPN from site A
to site B also provides connectivity from site B to site A, and nothing is needed to be configured
on site B.
Manual IPsec
You create an IPsec VPN tunnel between two peer routers over internet manually, from a local
router to a remote router that supports IPsec. Omada managed gateway on this site is the local
peer router.
Client-to-Site VPN
A Client-to-Site VPN creates a connection to the LAN from a remote host. It is useful for teleworkers
and business travelers to access their central LAN from a remote location without compromising
privacy and security.
The first step to build a Client-to-Site VPN connection is to determine the role of the gateways and
which VPN tunneling protocol to use:
VPN Server
The gateway on the central LAN works as a VPN server to provide a remote host with access to
the local network. The gateway which functions as a VPN server can use L2TP, PPTP, IPsec, or
OpenVPN as the tunneling protocol.
VPN Client
Either the remote user’s gateway or the remote user’s laptop or PC works as the VPN client.
