This section describes the connection configuration details for Site-to-Site VPN connection establishment
between 2 DEVG2020 GW devices. The LAN subnets of these 2 devices have to be in unique range for the
connection to be established successfully.
1. On the first DEVG2020 GW device,
navigate to the Advanced tab and select VPN > “Manage VPN” menu
on the left pane. Browse down to the Site-to-Site VPN configuration section of the page.
2. Enter an alphanumeric string (max 32 characters) in the Pre-Shared Key (PSK) field. Note that this PSK
field is unique to the Site-to-Site VPN configuration and should not be confused with the Remote client to
GW configuration.

i. Site Name
– this is a user friendly name to the connection entry
ii. WAN IP
– enter the remote GW WAN IP address.
iii. Remote Site IP address and Subnet

earlier, each of these 2 GWs in this configuration need to have a unique non-overlapping
IP address range

address range of 192.168.15.1, then you might choose 192.168.
