Are you sure those errors were not there before Faisal? This is a common issue with networks using VPN and even though they are listed as errors most likely they are false spoof alerts (unless your network is horribly misconfigured)

If this is the same situation as you are having it is safe to suppress the spoof messages. If not reply back with your network setup and I will continue to help you troubleshoot..
