cisco vpn & router

Hi i just purchased a d-link DI-624 router which has VPN Pass-Through.
My questions are:
Can I configure the router so that I can access my company's tiny term
application without going through the Cisco client first? Or do I
always need to start up the Cisco VPN client before logging on to my
office programs.
Basically I had an older Netgear which worked great, now my new d-link
says it has VPN Pass-Through, and wondering what more it can do for me.
Both connect to my office through Cisco vpn client.
Also My second question is there a way I can connect to my office
through vpn, and still access my internet? With both modems it seems I
can only do one or the other.
Thanks in advance?
