I have a rather large scale requirment that needs remote users to connect to a device hosted on a 3g router.

Example A user on an ADSL or other 3G connections needs to type in a IP address/dyndns address in a browser to connect to a device connected to the Host 3G router.

Problem is that Vodacom cannot offer me fixed IP's. With ADSL i just use a dyndns service to track the IP but the problem i have is that the 3G routers i will use will be moved around daily, sometimes multiple times in a day meaning the are recconecting and therefore changing IP's.

The only solution i can think of is to have Vodacom inform me of the re-connection IP via SMS/email so that we no what address to use to connect to again. They say they cant do this.

Has any one got any idea's?

P.S There will be no PC's connected to the 3G router, just an IP type appliance that we need to connect to.
 
If you apply for access to the unrestricted APN you will get a dynamic internet routable IP (like ADSL). Check it out here

If you have bigger plans you can also apply for your own corporate APN. But it costs a bit of money, but you can get fixed IPs.
 
My concern would be, that even if your router gets a routable IP address via the Unrestricted APN, the appliance that connects to it might still not be accessible.

Maybe I'm missing something here, but you just run DynDNS on the router and Bob's your uncle. Everytime your router connects it will update the DynDNS account. Your users just connect to the same URL.

The 3G router must be on the unrestricted apn to allow incoming connections.
 
i wasnt sure if the 3g routers supported dyndns services? still R&Ding....

Hmm...then, as in 'I Robot', you must ask the correct question :)

But, yes, they do. I use it like this all the time.

What is you app, how many concurrent users needing how much bandwidth?

Remember, you'll be using the 3G network in 'reverse' which means a max speed of 384Kb/s (on HSDPA) but at least there will be little to no contention...;)
 
the way i understood it is that the 3G IP assigned is not a proper public IP. I also thought that i would have problems with accidentaly disconnections and reconnections and not being able to get a routable dynamic IP back.

So as a Vodacom representitive are you telling me that i can just setup a DYNDNS service on the router and then no matter how many connections losses and power downs; upoon reconnection i will be able to connect back to the box via the DYNDNS address?

As already pointed out, you need to be using the [searchforum]"Unrestricted APN"[/searchforum] as well as DynDNS. Try it.

Yes, the 3G router will update the dyndns everytime it connects.

That's step one.

But you need to make incoming connections, for that you need to have incoming ports open. So, for this, you need the unrestricted apn.

Do both, configure dyndns and get the unrestricted apn configured and it'll all work.
