Default Gateway for VPN Traffic (VPNos 3.X)
The default gateway for VPN traffic policy allows the administrator to specify a gateway that is 
used for either decrypted traffic, encrypted traffic, or both. Beginning with VPNos 4.5, the default 
gateway for VPN traffic policy allows the administrator to specify a gateway that is used for 
decrypted traffic only.
This configuration is commonly applied to a VSU in the following topology:
Figure 27: Common Default Gateway for VPN Traffic topology
 shows the default gateway of the VSU as R
1
, the Internet gateway. The VSU is 
configured to protect several LANs on the other side of R
2
, the router on the private side of the 
VSU.
In this topology, the administrator configures R
1
 as the default gateway of the VSU and R
2
 as 
the Default Gateway for VPN Traffic with the decrypted box checked. Using this configuration 
and checking the decrypted traffic box, all decrypted VPN traffic would be forwarded to R
2
 and 
all encrypted traffic would be forwarded to R
1
. In this application, the Default Gateway for VPN 
Traffic removes the need for a configured static route on the VSU for each protected LAN.
Note:
Note:
Configured static routes take precedence over the Default Gateway for VPN 
Traffic.
