Routed VPN tunnels, with no tunnel IP

ArkwrightArkwright All-Knowing Sage ✭✭✭✭

In SonicOS we can create an IPsec policy with Policy Type "Tunnel Interface". Then create routes that use this interface. No need to create a interface on top of that with an IP address [but you can if you like].

Is this a Sonicwall-proprietary thing? If it's not, what's the name of it? Is it an "unnumbered VTI"?

    @Arkwright unnumbered VTI sounds right to me. I never used it for something else besides SNWL-to-SNWL, IIRC there was a Teldat/Bintec which worked too.

    I'am currently thinking about to have the VTIs numbered, because it gives more options, like binding a Network Probe to it and maybe have some simple VPN monitoring because of the weird SNMP options for that.
