Hi,

I am trying to find out a couple things about a telecom provider Digicel in Vanuatu. Does anyone know if there is a "public" APN in Vanuatu that allows for inbound traffic? I need to set up a computer so that we can dial into it, and was planning on using a 3G modem and Dyndns service.

I know that this kind of setup is common in NZ, but not sure about Vanuatu.

Thanks, John

Have you called the provider in Vanuatu and spoken to them?

I have emailed them and tried calling but waited for a long time, so wondered if anyone in this forum knew the answer. I do see that there is an APN to use:

but I don't know if it allows inbound traffic, or how to set that up.

Instead of "dialing into" can't you run LogMeIn on this PC? LogMeIn doesn't require inbound connections and will work just fine.

I see what you're saying, and think LogMeIn is a cool application also - but in this case the application is not a "PC" as in a windows PC. It's a small industrial computer that has a DHCP ethernet port, and communicates using ethernet on port 80.

I know that "internet" as an APN seems to work for a 2Degrees 3G modem in NZ, is that an international dejour kind of standard among wireless providers? I am new to it, but would imagine that providers would generally discourage it except for certain applications that need it. this is not a http server or anything but will provide status on a system in a remote location, very low bandwidth requirements.

You need an APN that gives a public IP. In NZ the "internet" 2degrees APN doesn't seem to do that and their old "direct" APN doesn't seem to be working as of yesterday. Not many providers have APNs with direct connections (ie Public IP). Your really need to talk to them.

Thanks Zeon, that makes sense. Is there another 2Degrees APN to test this here in NZ?

Your best option is to put a VPN capable router between your industrial PC and the 3G connection, and have that connect into a VPN server/router somewhere back in NZ.

Also, what's the PC running? Do you really want to expose it to the public internet?

Even if you get a Public IP address, there is still other things that could prevent you doing this. (Eg. port or protocol blocking).

Probably the only way you're going to know for sure is to do some testing.

Sounds like a good excuse for a 'business trip' to Vanautu to me!

The other thing that you will find is typically even if you are on a public IP. Your session will get bounced every 24 hours so you will get a new IP address each time. So it will need to "phone home" to say it's got a new IP. And if it's doing that wouldn't it be smarter to just run a reverse tcp session and keep it alive that way?

My feeling was that a mini router with DYNDNS on it would help with that. the actual control aspect of it is going to be used very sparingly, not a real-time situation as of yet. Thanks for the ideas!

in terms of a VPN, any ideas for something that runs on Debian?

Yea I like the intermediate router idea with VPN and DynDNS here. probably gonna be the best solution, especially if you can't get a Public IP. I'd still ery much suggest trying to get a public IP though.

There is an Open VPN package for Debian called, wait for it, 'openvpn'.

Or just look at a small router. Probably a Draytek 2130 would be a good start. It has USB ports for 3G 'backup' but with no other WAN connection will just use the 3G all the time. SPI firewall, VPN, DynDNS etc

was testing a TP-Link 3020 I think it was, seemed to work OK. as good or is reliability/security/feature set better in your recommended unit? Thanks.

Ok will check that strange and obliquely named VPN service out...advantages over say sshd?
