OpenVPN n parameters
Description
The text string is a friendly name to help identify this OpenVPN instance.
IP address a.b.c.d
This must be specified correctly. OpenVPN interfaces use a 30-bit mask. The first address is
the network address, the second address is the server address, the third address is the client
address, and the fourth address is the broadcast address. This address must be configured as
the second IP address in the block of four. For example, the IP address
192.168.0.1
, if
configured as a server, or
192.168.0.2
, if configured as a client.
Destination host a.b.c.d
Required only when the router is configured as an OpenVPN client. This is the IP address of
the OpenVPN server.
Link socket interface x,y
If configured, OpenVPN sockets are only allowed to/from this interface and the routing table
will be ignored. When set to
Auto
, the OpenVPN sockets use the routing table to identify the
best interface to use.
Get link socket source address from this interface x,y
The values in these two text boxes define the interface (
Auto
,
PPP
,
ETH
) and the instance
number of the interface to use as a source address for IP sockets when not using the interface
that the socket was created on.
Even when this parameter is not configured, the IP address from the interface on which the
socket was created will be used. The source address specified in this parameter will only be
used if it will cause the traffic to match an Eroute and therefore be sent using IPsec or GRE.
MTU
Used to set the Maximum Transmit Unit for the OpenVPN instance, in bytes. The default
setting is
1400
.
Metric
The connected metric, changing this value will alter the metric of dynamic routes created
automatically for this interface.
