I'm look for a Linux based Firewall Appliance that supports incoming iPhone VPN connections out of the box.
The rest here is the current status of my research into this topic.
Currently I'm using IPCop with a PPTP / L2TP addon currently to shield my home network and allow VPN connections with my iPhone. But lately I'm not that enthused with IPCop because of lacking updates as well as other problems (e.g. PPTP addon doesn't properly work with the newest IPCop version).
So I'm looking for another Firewall that has the usual firewall features, but the most important is a propert support for VPN connections from the iPhone. To my knowledge only PPTP / L2TP is the way to go when using Linux because of problems with IPSec. I've looked at the IPFire and Endian Firewalls, they are all nice and working, but neither supports PPTP / L2TP and the delivered IPSec implemenation cannot be handled by the iPhone.
Does anyone have suggestion for another Firewall appliance that supports this?
