Site to site VPM - mesh topology

Good afternoon,

 

I have several UTM sites currently connected via VPN in a star topology.  I'm looking at moving these to a Mesh topolgy, but I'm having trouble finding examples on how to do this.  Can anyone point me in the right direction please?

 

Thanks in advance.

  • Hi, Shaun, and welcome to the UTM Community!

    In fact, the star topology is the more-complex.  Mesh just means having a separate tunnel from each site to each other site, so I'm confused about what it is you're asking.

    Cheers - Bob

  • Ah - I see.  Sorry for the confusion.  I've always configured Sites in a star topology... ;)

    I think I was getting myself confused between a mesh topology and network availability groups - thanks for the clarification.

  • In IPsec site-to-site configurations where you have two WAN connections at site A, you will want to use an Interface Group in the IPsec Connection.  At site B, you will want to use an Availability Group in the Remote Gateway 'Gateway' field.  Be careful that the Availability Group has the same order as the Interface Group.  I'm using this approach in several places, including a client in Virginia with five locations where each has two WAN connections.

    Cheers - Bob
