Connect multiple HubVPN RMS at the same time

[Powidian]

Good morning,
I want to use the HubVPN of the RMS system to access a multitude of RUTXxx which themselves allow access to a fixed IP subnet which is always configured in the same way (subnet 192.168.1.x/24)
Thus, there will be a HubVPN dedicated to each RUTXxx with an internal IP route 192.168.1.100.

So, I end up with a configuration resembling this (we limit it to 3 VPNs):
HubRMS_1 ← RUTXxx_1 ↔ 192.168.1.100
HubRMS_2 ← RUTXxx_2 ↔ 192.168.1.100
HubRMS_3 ← RUTXxx_3 ↔ 192.168.1.100

Currently, I connect without problem via Linux command line individually with each HubVPN:
sudo openvpn --config xxxx.ovpn
My IP 192.168.1.100 works locally.

However, I need to keep all 3 VPN connections open at the same time on my Linux system. At this time a conflict occurs locally between the 3 IPs 192.168.1.100.

So I need the 3 IPs 192.168.1.100 to be remapped locally into a single IP:
local 192.168.11.100 = HubRMS_1 192.168.1.100
local 192.168.12.100 = HubRMS_2 192.168.1.100
local 192.168.13.100 = HubRMS_3 192.168.1.100

How should I run/configure openvpn locally?

Thanks in advance

Hello,

RMS VPN Hubs are used for layer 3 connectivity, which requires the devices to be on different networks. You can take a look at this forum post here for a workaround, but this is not recommended.

Kind Regards,

This is an interesting approach which, however, requires a small specific configuration for each RUTXxx (which is therefore no longer completely identical).
Anyway thank you for your help.

Hello,

I would suggest checking what can be done on your PC specifically in this case. You can try looking here, perhaps it will help.

Kind Regards,
