Node connection via cellular modem and OpenVPN anyone?

Hi all,

I need to run a node over a cellular data connection and have managed to get hold of a couple of Teltonika RUT105 3G modems:

http://www.4gon.co.uk/teltonika-rut105-p-5010.html

These devices support OpenVPN and I was wondering if it might be possible to use this to tunnel to one of my other Allstar nodes that has a regular Internet connection with a public IP address (in fact one of the sites has multiple public IP’s available).

Has anyone ever done anything like this and could give me a few clues as to how I proceed?

I’m assuming that the node at the end of the tunnel will need two ethernet ports, one for the connection from the 3G modem to come in on and another with a different public IP for the cellular connected node to be able to use.

Does this sound feasible?

I’d appreciate any help anyone can give as I’m not at all sure how to go about configuring OpenVPN to do this having never used it before!

Many thanks,

Matt

Better off using a Mikrotik router board with an LTE card then do pptp to some internet safe IP space.

This is what I do to connect my GB3EI Node in the Outer Hebrides. works well.

I can give you a config if required.

Problem with 3/4G dongle is they do Internal NAT and you cant do the port forwarding.

"Problem with 3/4G dongle is they do Internal NAT and you cant do the port forwarding."

Just put the OpenVPN client on the repeater side of the link (where the carrier is employing NAT) and have it establish the tunnel to the other end of the link where you have the public IP and can port forward to the OpenVPN server... Hopefully the wireless carrier is not blocking port 1194 (they should not, but...). If they do you can configure OpenVPN to use port 443...
