For some time we have experienced problems with the following error-message from the Cisco VPN client running on Windows Vista:
reason 403 unable to contact the security gateway
Enabling the log on the client shows this error:
Unable to bind to IKE port. This could be because there is another VPN client installed or running. Please disable or uninstall all VPN Clients other than the Cisco VPN Client.
Following another help-article on the Internet, we stopped this service running on the computer:
IKE and AuthIP IPSec Keying Modules
After stopping this service, the user was able to contact and logon to the gateway. You should however note, that you should not stop the service, if the protocols are being used on your network.

To resolve issue number 2:
Find the publishing rules used to publish Exchange Outlook Web Access, go to Properties -> Application Settings – and these settings worked for me:
