Question : IPSEC VPN vs SSL VPN


I am currently using a VPN IPSec based VPN.
I have the following problem only one user at the time may use the VPN because of NAT.

Is SSL VPN may resolve the problem of multiple users using a SSL VPN connection trough a NAT Firewall ?

You use the same tools that Apple uses themselves, namely XCode.  All you have to do is to download additional SDKs for free from

This is all that you need in theory to start developing complete high quality applications.

There are of course a whole plethora of other programs that can also be helpful, such as Photoshop/Gimp etc, 3D software, if you are into making games and so on.

There are also libraries/frameworks that will help out, such as cocos2d if you are into making 2d games etc.  Some are free, and others will cost you money.

But you are right in your assumption that all you need is a mac and a developer account.  XCode and sdks can be downloaded from
