ITShield Networks Inc. (http://www.itshield.com) released a wonderful firewall. It is very easy to install and manage, and generates a descriptive log. ITShield firewall is totally different from the Stateful Inspection firewalls, such as IPCHAINS/IPTABLES and CheckPoint. ITShield Firewall, a transparent firewall, contains the advantages of all three critical firewall architectures - packet-filtering, Stateful Inspection, and application gateway firewall. By using some advanced technologies, ITShield Firewall can handle more than 5000 TCP sessions, unlimited UDP sessions, and unlimited IP sessions at application-level in parallel. Because application proxy provides the highest level of security and flexibility, ITShield Firewall handles all the sessions in application-level by default. Furthermore, ITShield Firewall can drop the unwanted requests at packet level. If the high-speed network traffic keeps the firewall very busy, the administrator can enable Stateful Inspection. ITShield firewall supports IPSEC VPN and PPTP VPN. They are very easy to set up. It also provides user authentication so that you are still safe to use ftp and telnet to access your internal resources. ITShield firewall provides a secure remote administration tool so that you can manage the firewall from the unsecure network - Internet.
