I can't connect
If you cannot connect to the server running iVPN from your client make sure you have done the following:
- Forwarded TCP port 1723 for PPTP, or UDP port 4500 and 500 for L2TP IPSec, through any firewalls you may have, this includes Mac OS X's built-in software firewall and any NATs or routers you may have. Please read your router's manual on how to forward ports. Also, some routers have a VPN pass-through feature; if you have this, make sure you enable PPTP or L2TP and IPSec pass-through on both the client-side router and server-side router. To check that ports are open, search Google for an open port checker.
- Make sure Back To My Mac is not enabled on your Mac as this can interfere with IPSec negotiation. You must restart you router after enabling or disabling Back To My Mac to reset any ports that Back To My Mac had automatically forwarded.
- Check that 'Activity Monitor' lists the process 'vpnd' (and 'racoon' if L2TP IPSec was chosen) To be able to see these processes, the 'Show' menu must be set to 'All Processes'. If not they are not listed, email me with your situation.
- Check that you do not have any other software or hardware that could interfere with the VPN server. Little Snitch is a common cause for any network related problems.
- Make sure you have entered the settings correctly in your client.
