10.1.4. VPN Pass Through
IPSec Pass Through
If this option is enabled, the PC is allowed to use VPN-IPSec
packet to pass in order to connect to external VPN device.
Fixed Source Port
(Future Feature)
Change Source Port
(Future Feature)
This option is only required when having VPN connection with
Cisco VPN Server and Client. Because VPN Server does not
accept two connections with the same IP and same source port,
the second connection needs to change source port from UDP
500 to the other random port. If choosing Fixed Source Port, the
second connection will still keep the connection with UDP 500.
PPTP Pass Through
If this option is enabled, the PC is allowed to use VPN- PPTP
packet to pass in order to connect with external VPN device.
L2TP Pass Through
If this option is enabled, the PC end is allowed to use VPN-
L2TP packet to pass in order to connect with external VPN
device.
After modification, push “Apply” button to save the network setting or push “Cancel” to keep the
settings unchanged.
