I've a SCADA who's a VPN client from a VPN HUB (SCADA-HUB). The SCADA communicates with all devices (20x) within the same VPN HUB (SCADA-HUB), and that's working great. Within all these devices there's 2 that required to communicate together (LAN to LAN), but all other devices most not being able to communicate with those two. If I enable LAN-to-LAN with the devices in the (SCADA-HUB) all other devices in the same VPN hub gain access to it...
I've created a 2nd VPN hub with only these 2 devices with the LAN-to-LAN enabled.
Everything works but randomly... when one of the devices gets connected both VPN-HUB push routes to the devices. Both VPN hub pushes the same IPV4-routes to the same device. When there's a IPV4-Route conflict, it simply overwrites it (normal).
When you look at the attached picture, sometime the 10.100.10.0/24 routes is with the (tun_c_rms_ZEy....) network and sometime the it is with the (tun_c_rms_mGw...) network.
Is there a way to force the configuration has the picture... to always use the same route ?
Is there other solutions ?
