Hub & Spoke VPN routing (3 sites)

[exactiv]

Hi there,

I have a network organised as follows

HQ 192.168.5.x/24
Branch1 172.17.15.x/24
Branch1 10.10.10.x/24

I have IPSEC vpn tunnels operating from the branch offices to HQ. I now want to route from branch to branch via the hub. (see attached image for an example)

The device at HQ is a Sonicwall TZ180, Branch1 is a Sonicwall TZ150 and Branch2 is a Sonicwall TZ100.

I'm not sure what to do to be honest! I attempted to use static routes but got lost. Any help would be appreciated. Even a shove in the right direction would be useful.

Thank you!

I have solved it with the help of Sonicwall Support. They are very helpful I might add.

Only one of the devices has the new enhanced sonic os, the others do not as they are older.

For the hub I needed to set Forward packets to remote VPNs on the advanced tab

For each of the spokes needed to have the destination network of the other spoke added.

It all works perfectly now.
