Do I do this on the workstation

Yes - the VPN client has detailed logging capabilities.

After setting that you told me to do, it is still unable to produce any logs.

Post the debug log of the client - set the logging levels:-

IKE - 3 = high

IPSEC - 3 = high

Firewall - 3 = high

OK - did you actually enable logging? You have to enable it on the client for the logs to be captured?

I have attached the logs to this message. Please have a look and is if you can find any issue.

Many Tnaks.

Initializing CVPNDrv

You habe an issue with the install or the machine is using those ports for something else. I suggest you remove the software and try re-installing.

I have reinstalled it couple of times now and its still not working.

There is a possible issue with a feature called "Back To My Mac" which allows two Macs running OS X 10.5+ (Leopard) remote access to each other via PnP enabled routers.

This has been disabled as have all the sharing functions on this iMac.

I also have a Windows VM (on VMware Fusion) that shares the network capabilities of the host but this is also offline.

Something on the machine is stopping the client from working!

Any updates? I have the exact same issue and have tried several methods to fix the problem.

The thing that doesn't make sense is that I can find nothing that is already bound to port 500. I've used netstat -af and lsof -i:500, but nothing is using it already. I even got on with Apple support, and they had no suggestions.

The only other option I can come up with is to reinstall OS X (I've already tried repairing permissions), but before I do that I want to see if anyone has another idea.

I should also mention that I added an extra setting to the end of the pcf file ("UseLegacyIKEPort=0"), which somehow gets past the problem and lets me connect, but I cannot make http requests to my company's intranet.
