I have a LinkSys RVS4000 VPN router. I have been having problems trying to connect to the router using the Quick VPN client. I have seen in a post on this forum that the Quick VPN client won't work with any other VPN client installed on the same computer. I have to use the Cisco Systems VPN Client, version 4.6.04.0043, for access to my work's VPN. Can I use this client instead of the Quick VPN client to access the RVS4000 router? If so, how do I need to configure it?
