In SonicOS versions 5.6 and higher, VPN Tunnel Interfaces can be configured for advanced 
routing. To do so, you must enable advanced routing for the tunnel interface on the Advanced 
tab of its configuration. See 

 for more information.

After you have enabled advanced routing for a Tunnel Interface, it is displayed in the list with 
the other interfaces in the Advanced Routing table on the Network > Routing page.

To configure Advanced Routing options, click on the Configure RIP or Configure OSPF icon 
for the Tunnel Interface you wish to configure.

The RIP and OSPF configurations for Tunnel Interfaces are very similar to the configurations 
for traditional interfaces with the addition of two new options that are listed at the bottom of the 
RIP or OSPF configuration window under a new Global Unnumbered Configuration heading.

Because Tunnel Interfaces are not physical interfaces and have no inherent IP address, they 
must “borrow” the IP address of another interface. Therefore, the advanced routing 
configuration for a Tunnel Interface includes the following options for specifying the source and 
destination IP addresses for the tunnel:

IP Address Borrowed From - The interface whose IP address is used as the source IP 
address for the Tunnel Interface.

The borrowed IP address must be a static IP address.

Remote IP Address - The IP address of the remote peer to which the Tunnel Interface is 
connected. In the case of a SonicWALL-to-SonicWALL configuration with another Tunnel 
Interface, this should be the IP address of the borrowed interface of the Tunnel Interface 
on the remote peer.

The IP Address Borrowed From and Remote IP Address values apply to both RIP and 
OSPF for the Tunnel Interface. Changing one of these values in in RIP will change the value 
in OSPF and vice versa.
