RUT906 Static Route or VPN

Dear Experts,
I am trying to create a network between 2 RUT906 devices with firmware version RUT9M_R_00.07.18.3 according to the attached architecture.
My simple architecture is as follows:

2604571f1e50e1f6b1cdde3727f2d547ad7c3055
2604571f1e50e1f6b1cdde3727f2d547ad7c30551496×587 54.3 KB

  1. What do we need to do to connect the PLC device to the Scada device B?
  2. Also, what do we need to do to connect from Device 2’s WAN IP address to the SCADA device connected to Device 1?

Hi…

Are you using a VPN, like IPSEC/ZeroTier or ???

Because… You cannot have the same lan ip address of each side of the VPN!

Can you split the each side of the network, changing only the netmask?

Greetings,

Could you please clarify the purpose of the LAN cable between the routers? Are the routers connected LAN-to-LAN or WAN-to-WAN?

Also, is a mobile connection being used in this setup?

Greetings,

The purpose of the LAN cable between the routers is:
1- To allow Device 2 to access the device connected to Device 1.
2- To allow Device 1 to access the device connected to Device 2.
Currently, the cable is connected as LAN to LAN. Since both devices have mobile connectivity, I couldn’t connect them as WAN to WAN.
I think we can solve this using a VPN connection without the cable, but how can we do it without a VPN connection?

Each router has its own mobile connectivity.

Best Regards,
Mustafa

Hello,

  1. Both routers are in identical subnets, and routing will not function properly:
  • Use 172.62.147.x for the RUT906 Device 1 (change the SCADA accordingly if it’s not on DHCP, same with the gateway IP addresses)
  • Use 172.62.148.x for the RUT906 Device 2 (change the PLC accordingly if it’s not on DHCP, same with the gateway IP addresses)
    2.Add a Static route under Network → Routing → Static Routes on the RUT906 Device 1:

Port forwarding would usually do the trick: Port Forward: Accessing LAN devices - Teltonika Networks Wiki
