DDNS update via Vodacom network

[shikarssj]

I have been using the ChangeIP service to host a dynamic DNS server via the GPRS network.


I am working on an embedded project and have written my own HTTP client to send updates via HTTP.

I am having a very weird problem.

If I get assigned a network IP address in range 192.XXX.XXX.XXX, I get the HTTP response from changeIP for successful update. This uses the "internet" APN from Vodacom

However, if my network assigned IP address is in range 41.192.XXX.XXX, I do not get the successful HTTP reply. I think the update still registers on changeip website. However, if I use bad authentication details, I receive a HTTP reply for bad authentication from changeIP. This uses the "UNRESTRICTED" APN.

Same client works fine via MTN network.

Is it possible that somewhere between the website, Vodacom network and my server that a router blocks HTTP 200 responses from changeIP website?

Any help will be appreciated.

Unsolicited inbound connections are blocked on the internet APN. You need to activate the unrestricted APN (free). Search in the forum for more details.

@morkhans, he said "This uses the "UNRESTRICTED" APN."

@shikarssj, I've had to write a DDNS updater that used DynDns.com and it worked fine on the unrestricted APN. Also via HTTP. Got a response for valid and invalid updates.

Oops my bad Thanks for pointing that out.

FWIW there is a local dyndns service -> http://www.dynami.co.za/

Hi,

I am trying to setup remote access to a network via a Linksys WRT54G3G.
I have obtained the unrestricted APN an done the setup on the router. I have also setup the dynamic DNS with DynDNS and the router reports that it is successfully setup. If I ping the DynDNS hostname from another PC connected via ADSL it resolves to the correct IP as reported on the router but I do not get any response from the router. I have a PC connected to the Linksys router and I can access the internet etc. so the connection is fine. Anything else I have to do in order to see the router via the internet?

By the way, under APN configuration on the router I have 'unrestricted' as APN name . What do I have to put in as User Name and Password?

Any help will be greatly appreciated.

pings to the router are most likely blocked from the outside. You need to check the firewall settings on the router.

The username and password fields can be left blank.
