4. The loopback interface is configured for a virtual private IP address to use for the IP SEC
encryption
To configure the loop back address, go to DATA / Loopback Interfaces.
Then select enable (if not by default), select address to type “static” and then enter a unique private IP
address. This IP has to be unique to EtherSpeak – and should also be unique from your LAN network
of IP addresses. Please consult with EtherSpeak about which loopback address you would like to use
as each address has to be unique to EtherSpeak. Ensure Dynamic DNS is disabled, then click apply.
After the physical connections and the loopback address is established, go to Data / VPN / VPN Peers
and type a name for the tunnel. In this example, we typed “EtherSpeak” and assigned the VPN to the
Untrust interface and the statically assigned IP address.
