A new remote configurable firewall system for home-use gateways

We have developed a new remote-configurable firewall system that provides secure and easy-to-use access to home-network appliances such as network cameras, PVRs, and home file senders, through the Internet. Accessing the home-network from the external network is not still popular for low-end users. This is mainly because of the complex configuration of firewall/NAT policy and of the anxiety for security vulnerability which can be caused by statically opening the external ports. To solve these problems, our system provides easy-to-configure, easy-to-use remote accessing method. With a simple Web browser operation, remote users can dynamically open and close the firewall of the home gateway. The firewall rule creation is based on an authentication of the remote client, and thus only packets from the authorized client can pass through the firewall. The system also provides simple policy-template creating system that provides easy installation of the home-network appliances.
