Configuring the VPN Passthrough
Cisco ISA500 Series Integrated Security Appliance Administrator Guide 268

Configuring the VPN Passthrough
You need to configure VPN passthrough if there are devices behind the security
appliance that need to set up the VPN tunnels independently, for example, to
connect to another router on the WAN.
STEP 1 Click VPN -> Passthrough.
The Passthrough window opens.
STEP 2 Enter the following information:
• L2TP: Click On to allow L2TP clients at LAN site to connect to a L2TP server
on Internet, or click Off to disable it.
• PPTP: Click On to allow the hosts at LAN site to establish a tunnel with a
PPTP server on Internet, click Off to disable it.
• IPSec: Click On to allow the IPSec traffic to pass through the security
appliance over the IPSec VPN tunnel, or click Off to disable it. The VPN
tunnel can be established by a Site-to-Site VPN session or a Cisco IPSec
VPN session.
STEP 3 Click Save to apply your settings.
Viewing the VPN Status
Use the Session Status pages to view the status and statistic information for IPSec
VPN and SSL VPN sessions, and manually connect or disconnect the VPN tunnels.
It includes the following sections:
• Monitoring the IPSec VPN Status, page 269
• Monitoring the SSL VPN Status, page 270
