Question

Hello,

I have two Teltonika RUT950 Router and looking out for Automated NAT traversal and hole punching through firewalls!

RUT1 (Lan IP: 192.168.1.0/24) is on a general public Internet and do not have a static public IP address;

RUT2 (Lan IP  10.179.253.0/24) is on a head office LAN behind  a firewall and  NAT translation of  LAN IP

Is it possible to configure "Automated NAT traversal and hole punching" with the two RUT950 routers to be able to route traffic between the two LANs  without any configuration of public IP addresses on the two routers ?

Hello,

Can a site-to-site layer 2 VPN be established/configured with two RUT950 routers at different locations(different Internet without public IP addresses) using their MAC addresses and Serial number or either of both?  

This could be likened to  RMS service bridging tunnels established between two RUT950 devices and RMS "hanging up"  for the final secure tunnel between the two devices.

Hello,

Do I understand correctly? You want RMS to work as a middle man in bridging two L2 networks behind two RUT950 both of which do not have public IP addresses? If yes, currently RMS does not have such feature. Have you looked at third party services such as Zerotier?

Hello,

We do not have a specific example on how to do that (Connecting two locations together without having a public IP address is quite unorthodox)

But you could try searching for an example in OpenWRT forums, because our devices are running a fork of it.

Specifically this thread: https://forum.openwrt.org/t/how-to-connect-two-routers-which-are-physically-far-away/2743/6

One person suggested to use ZeroTier service, which I think would be a quick and simple solution to your use case.

You can download ZeroTier service as an additional package in System > Package Manager

Also, you can find a configuration example here: https://wiki.teltonika-networks.com/view/ZeroTier_One_VPN_configuration
