In this example there is more equipment connected behind the router, using a Switch. Every device con-
nected behind the router has its own IP address and this is the address to fill in the Server IP Address field
in the NAT configuration. These devices are all communicating on the port 80, but you can set the Port For-
warding in the NAT configuration – see Figure "Example 1 – Topology of NAT configuration" site 42 –

fields. It is now configured to access 192.168.1.2:80 socket behind the router when
accessing 10.0.0.1:81 from the Internet and so on. If you send the ping request to the public IP address of
the router (10.0.0.1), the router will respond as usual (not forwarding). If you access the IP address 10.0.0.1
in the browser (it is port 80), nothing will happen – there is neither 80 port in Public Port list defined nor you
have checked the
Enable remote HTTP access on port 80. And since the Send all remaining incoming pack-
ets to default server is not enabled, the attempt of connection will lead to failure
.

Item
Description
Description
Description (or name) of tunnel
Protocol
Protocol by which the tunnel will communicate.
•
UDP – OpenVPN will communicate using UDP
•
TCP server – OpenVPN will communicate using TCP in server mode
•
TCP client – OpenVPN will communicate using TCP in client mode
UDP/TCP port
Port by which the tunnel will communicate.
Remote IP Address
IP address of opposite tunnel side (domain name can be used).
Remote Subnet
Network IP address of the opposite side of the tunnel.
Remote Subnet Mask Subnet mask of the opposite side of the tunnel.
Redirect Gateway
Allows to redirect all traffic on Ethernet
Local Interface
IP Address
IP address of the local side of tunnel.
Remote Interface
IP Address
IP address of interface local side of tunnel.
Ping Interval
Parameter (in seconds) defines how often the router will send a message to the
remote end to verify that the tunnel is still connected.
Ping Timeout
Parameter which defines how long the router will wait for a response to the
ping (in seconds).
Ping Timeout must be larger than Ping Interval
.
Renegotiate Interval
Sets renegotiate period (reauthorization) of the OpenVPN tunnel. This parame-
ter can be set only when
Authenticate Mode
is set to
username/password
or
X.509 certificate
. After this time period, the router changes the tunnel encryp-
tion to ensure the continued safety of the tunnel.
Max Fragment Size
Defines maximum packet size
