The DA-660 does NOT support SNMP trap.
OpenVPN
OpenVPN provides two types of tunnels for users to implement VPNS:
Routed IP Tunnels
and
Bridged Ethernet Tunnels
. To begin with, check to make sure that the system has a virtual device
/dev/net/tun. If not, issue the following command:
# mknod /dev/net/tun c 10 200
An Ethernet bridge is used to connect different Ethernet networks together. The Ethernets are
bundled into one bigger, “logical” Ethernet. Each Ethernet corresponds to one physical interface
(or port) that is connected to the bridge.
On each OpenVPN machine, you should generate a working directory, such as
/etc/openvpn
,
where script files and key files reside. Once established, all operations will be performed in that
directory.
