Sure it's possible.....Both the uBR924 (http://www.cisco.com/cable/products/ubr924.html) and the 800 series (http://www.cisco.com/warp/public/cc/pd/rt/800/) support VPN IOS according to these links. I would say its a standard VPN configuration even though Ive never done it. The only problem is, if your cable provider installed the modem, they might not let you into it to configure it and they probably dont support VPNs from it (split tunneling has to be configured too for your normal Internet traffic to go out normally) so you might have to use the VPN client software instead as a tunnel end point.
