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.
