How do I pass traffic through a central UTM from two separate sites?

Hello MarkBruchkowsky1,

you have to put the Remote Lan on the other site B/C from the vpn tunnel and also the local Networks on A

E.g. Site A/B

For Site A:
Local Networks
Site A
Site C

Remote Networks
Site B

For Site B:

Local Networks:
Site B

Remote Networks:
Site A
Site C

The same thing you have to do for Site A/C

Afterwards you yust have to set firewall rules

Source:
Site B
Site C

Services: Any

Destination:
Site B
Site C

Thank you for the assistance DKNL. Unfortunately, having gone through all of those steps, I am still unable to ping Site C from Site B.

For ping you have to set the following options

Network Protection

Firewall -> ICMP

Allow gateway forwards pings

These must be done on all firewalls

Hi, Mark, and welcome to the UTM Community!

I didn't look closely at the instructions above, but my impression was that you should have connectivity.  If not, compare to Hub and Spoke Help.

If you have connectivity but can't ping, it's a different problem.  At some point, the settings on the ICMP tab only applied to outbound traffic and a separate firewall rule was required.  I don't know if it's still the case, but you might try a rule like '{B & C} -> Ping -> {B & C} : Allow'.

Please let us know if that resolves your issue.
