So how is the Cisco VPN client configured? If you worked before, then your ISP is allowing this traffic, and you do not have any firewalls, so it has to be the software.
Were you given a file to import into the VPN client for remote access, or are you manually configuring the client?
It seems to me your problem lies in the configuration of the Cisco VPN software. Do you know someone else who is connected properly using the same software? If so try and copy their settings.
