● Authentication
Specify the method for calculating the checksum.
– SHA256 (default)
– SHA384
– SHA512
– SHA224
– SHA1
– MD5
● Use LZO
When enabled, the data is compressed with the LZO algorithm.
● Auto Firewall Rules
– Enabled
For the VPN connection, the firewall rules for access from "External" to "Internal" and
vice versa are created automatically. In addition to this, access from the device to the
outside is allowed. You can enable access to specific services of the device under
"Security > Firewall > Predefined IPv4". Ping is enabled by default.
– Disabled
You will need to create the suitable firewall rules yourself.
● Enable NAT
With this setting, you enable automatic IP masquerading for this interface. The local devices
are not directly reachable from the outside, but only via the IP address of the interface. The
local devices can, however, connect to the devices downstream from the OpenVPN server.
You will find more information on NAT in "Technical basics > NAT (Page 45)".
● Timeout [min]
Specify the period of time in minutes. If no data exchange takes place, when this time has
elapsed the VPN tunnel is automatically terminated.
