The EMG loads a subset of the available
strongSwan plugins
. If an option is given in a custom
ipsec.config file that requires a plugin that is not loaded by the EMG, this may cause an error
during tunnel negotiation. The loaded plugins can be viewed in the VPN Status when the VPN
tunnel is enabled.
Sample ipsec.conf files are provided in the EMG online help files for a variety of tunnel
configurations and peers. The strongSwan Wiki also provides a variety of
usable examples
and
sample configurations
, in addition to interoperability recommendations.
Depending on the VPN configuration, it may be necessary to enable IP Forwarding or to add static
routes; in some cases traffic may not be passed through the tunnel without enabling IP Forwarding
or static routes. Refer to the VPN routing table that is displayed with the VPN status.
A watchdog program is automatically run when the VPN tunnel is enabled. This program will
detect if the VPN tunnel goes down (for reasons other than the user disabling the tunnel). The
watchdog program will:
Generate a syslog message when the tunnel goes up or down
If traps are enabled, send a slcEventVPNTunnel SNMP trap when the tunnel goes up or down
If an email address is configured in the VPN configuration, send an email when the tunnel
goes up or down
If enabled, automatically restart the VPN tunnel
When using VPN with Network Fail-over, the Local IP Address should not be configured for the
VPN tunnel. This will allow strongSwan to automatically determine the IP address on the local
(console manager) side of the tunnel based on the network configuration during both fail-over and
fail-back.
VPN tunnels over an console manager Ethernet interfaces that is configured with an MTU less
than 256 may experience issues (traffic loss, etc).
To set up a VPN connection:

Network
tab and select the
