For the last few days I’ve been scratching my head on a particularly knotty problem — configuring iPhone 3G to access our corporate VPN over 3G wireless. Rogers, bless their hearts, hasn’t made this easy. By reading the marvelous Howard Forums, visiting the Apple store in Toronto for help, and checking Apple’s support boards, I’ve managed to make it work with these three steps:
1. You will need the VPN option attached to your data account. Phone Rogers, speak to a CSR, and ask them to add this option. This allows you to access the Rogers vpn.com APN. You need this because internet.com, the standard iPhone APN, is behind a NAT.
2. Next you need to change the APN from internet.com to vpn.com. There is no option to do this on iPhone, because Rogers has disabled it. Nevertheless, you can visit http://www.unlockit.co.nz which is a web site that will send you a new profile that you can install on your device. Use APN vpn.com, username wapuser1 and password wap.
3. set up your VPN. You will need user names and passwords from whomever manages this stuff at your organization. AND you will need to set the “send all data” setting to off.
Now for the bad news. Having done this, you may find (as I have) that you’re no longer able to set up a VPN connection over WiFi.
