Task Description
Step 5
Create the following two IP Routes on
IPO_CO:
(1)
•
IP Address
= 192.168.50.0
•
IP Mask
= 255.255.255.0
•
Gateway =
<un-configured>
•
Destination =
L2TP
(2)
•
IP Address
= <un-configured>
•
IP Mask
= <un-configured>
•
Gateway =
217.37.65.123
•
Destination =
LAN2
(1)
The default route pointing all traffic into the
L2TP Tunnel.
(2)
A 32 bit route to the tunnel endpoint. A 32 route
is only for a single IP address.
Step 6
Create the following two IP Routes on
Branch No. 1:
(1)
•
IP Address
= 192.168.43.0
•
IP Mask
= 255.255.255.0
•
Gateway =
<un-configured>
•
Destination =
L2TP
(2)
•
IP Address
= <un-configured>
•
IP Mask
= <un-configured>
•
Gateway =
217.37.69.118
•
Destination =
LAN2
These routing entries will allow the tunnel to
forward traffic, destined for the remote network,
to the local VPN router.
Step 7
Checking to see if the Tunnel is up.
Using Ethereal, check packet exchanges are
occurring in the L2TP Tunnel.
Use SysMonitor to view PPP packet
exchanges. PPP echo Request /Reply packets
will be see (if selected) when the L2TP tunnel
is active. They will also be seen when the
active L2TP tunnel is protected by IPSec.
