Setting up the network
82 Avaya VPNmanager Configuration Guide Release 3.7
The Network/Mask Pairs for this Hop list indicates the static route destination address. You can
build a static route table with up to 32 network address/mask paris. This limit allows for any
combination ranging from a single router with 32 network address/mask pairs to 32 routers with
a single address/mask pairs.
To build a routing table using the default gateway:
1. From the Configuration Console Contents column, select the security gateway you want to
configure.
2. Click the Routing tab to bring it to the front.
3. In the Default Gateway area, select the Enable box to enable the default gateway.
4. Enter the IP Address for the default gateway.
5. In the Use This Gateway For area, select one of the following:
●Decrypted Traffic
●Non-VPN Traffic
6. Select the Enable VPN Traffic Auto Forwarding box to disable traffic auto forwarding.
If an SG receives a VPN packet that is not destined for the protected network, the SG will
automatically forward this packet to the configured remote TEP. By default, the Enable VPN
Traffic Auto Forwarding box is selected, or checked.
To disable the automatic forwarding of packets, the Enable VPN Traffic Auto Forwarding
box should be un-checked.
When the VPN traffic auto forwarding is disabled, the SG will divert the packets to the
private interface. By redirecting the packets to the private interface the pack ets can be
monitored by Intrusion Detection Systems software before sending the packets to the
remote TEP on the private network.
Before disabling VPN traffic auto forwarding, confirm that a VTDR or static route is
configured on the private interface. If a VTDR is not configured on the private interface, the
redirected packet will not be sent back to the SG to be forwarded to the remote TEP.
7. In the Static Routes area, click Add to start the Static Route Configuration Wizard.
