UserGate Proxy’s built-in firewall provides the additional protection of an Internet gateway to prevent hackers and other intrusions by blocking traffic going through particular ports (TCP, UDP, or any other IP protocol).

The UserGate firewall processes packages that were not processed by NAT rules. If a package is processed by the NAT driver, it will not be processed by the Usergate firewall.

Ports specified in the proxy settings (HTTP, FTP, Socks etc.), as well as ports specified in Port Mapping are included in automatically generated firewall rules (type auto).

This function binds any port of a local Ethernet interface to a certain port of a remote host. Assigning ports is usually used for specific applications such as netbanking, remote control software and others when it’s necessary to forward all calls going to some port number to an IP address on the local network.

UserGate Proxy makes it easy to create a set of traffic rules. It takes just a few minutes to set up the firewall to connect a network to the Internet. Rules are created on just one server machine, so administrators can be sure that security is not compromised by settings made by individual users on their local computers.
