Hey All,

Our users connect back to the office through a PPTP vpn when connecting through iPhones on XT. Normally works fine.
All of a sudden today none of our users can connect.

If I connect through vodafone all is working as expected. Is anyone else using a PPTP vpn on XT?

Cheers,

M

The iPhone would have had its APN set back to wap.telecom.co.nz. Go to APN settings and re-set it to internet.telecom.co.nz. It will periodically screw up and change it back, so rinse and repeat. Also happens on Vodafone. Same issue occurs with Windows Phones.

Hi, I had the same issue for numerous users connecting to either PPTP or L2TP IPSEC VPN's via iPhones & iPads 3G through the Telecom XT network.

I tried changing the APN from wap.telecom.co.nz manually to either internet.telecom.co.nz or direct.telecom.co.nz, worked a couple of times and then would revert back to wap.telecom.co.nz even though it displayed on the iphone internet.telecom.co.nz, someone mentioned in another post how to check which APN it is actually using by checking ip address.

But then I was submitted a KB from Telecom which said to change the APN via iPhone Configuration Utility and d/l to the iphone... very simple to setup & use and I have done it to several iPhones & iPads 3G and haven't had any more issues... even though it still says wap.telecom.co.nz under network settings in the iPhone 'Go Figure'.

From Telecom...

If attempting to connect the iPhone itself via their VPN they will need to use
the iPhone configuration utility to create a customer profile with the
direct.telecom.co.nz APN and load it onto the iPhone. This is not a work around
it is the Apple supported method to change the APN.

You shouldn't need to use the direct APN, internet should suffice. Direct actually puts your phone directly, unfirewalled, on the public internet with its own public IP address. Bad!

Yeah I had been told that as well so am using internet.telecom.co.nz and all working well.

To add to what freitasm said... just imagine having to pay 10c/MB for a DDOS on your phone. Yeah, it's entirely possible.
