Sm@rt server or remote connection to Siemens Unified

Hi there,

I am trying to connect remotely to a Siemens TP Unified panel.

I have setup a route on my RUT200.

Internal IP-adress of Siemens TP is 192.168.1.12.

When I run VPN, I can only connect through 192.168.255.10 which is some shadow IP adress.

Issue is that I cannot connect through HTTPS, I tried to forward port 443 from outside to 192.168.1.12, port 443. No luck.

Also tried with Sm@rt server, port 5800 and 5900. No luck.

What am I doing wrong?

How do I get HTTPS activated?

Browser states certificate is unvalid.

I can connect locally through both https and Sm@rtServer.

I am very new to Teltonika, so please ask if more details are needed.

Greetings,

Could you please clarify which VPN you are using to access the device remotely?

If you are using the Teltonika RMS VPN Hub, please follow the setup instructions provided here: RMS VPN Hubs - Teltonika Networks Wiki

When adding a route, you can specify the entire subnet using the 255.255.255.0 subnet mask.


If you only need a route to a specific IP address, please use the 255.255.255.255 mask instead.

Additionally, please try enabling masquerading for the LAN zone. You can do this by navigating to:
Network → Firewall → Zones .

At the moment, the current configuration is not entirely clear. You mentioned that you attempted to use port forwarding, which would not be necessary if a VPN is configured correctly. To help us better understand the setup, could you please provide screenshots of your current configuration? Screenshots of the panels configuration (including default gateway settings, etc.) would also be very helpful.

Best Regards,
Justinas

Thank you for your reply.

I am using Teltonika VPN. I get same result with OpenVPN.

I changed subnet to 255.255.255.255 and masquerading to on under zones.

No change, I can connect to 192.168.255.10 and do get a hold of 192.168.1.12.

Issue is that https redirects to http when I connect through VPN. Siemens Unified does not accept http due to error in transfer of certificate through the VPN.

So I can open landing page in http. The link to login is in https, but changes to http. And from then on, it is an ongoing loop.

I can login locally through https.

Hello,

  1. First, please clarify whether you’re using OpenVPN or RMS VPN Hub as these are configured separately, and quite differently (one is harder, one is easier to configure). This would help me to troubleshoot the issue further.
  2. Next, if you’re using the Teltonika RMS VPN application, could you please try to use OpenVPN Connect application instead to see if that resolves the issue?
  3. More so, if you’re using RMS VPN Hub, please delete the Static Route you have in your WebUI, as that is not needed.
  4. Also, if you have a separate OpenVPN configuration on your device that does not come from your RMS VPN Hub (which is automatically pushed onto the device) - kindly either delete it, or disable it so it doesn’t hinder the connection.

*Additional note - no port forwards, traffic rules & such need to be changed, at most, you’ll just have to enable Masquerading under Network → Firewall → Zones, specifically for the LAN=>WAN (first one in the list) zone.

Please also try re-pushing the OpenVPN configuration onto your device from the RMS VPN Hub configuration menu:

M.
