Internet access restriction is a typical task of a proxy server. For this purpose there are “Connection – Close” rules in UserGate. Working with the proxy server (HTTP, FTP), you may specify the resource domain name (URL) as well as its IP address. UserGate Server can implement filtering by a URL fragment (“Whole page” item), by address part (“Server address” item) or by document address (“Document address” item).

Figure 20. URL filtering settings.

When specifying an IP address you may choose “Source IP address”, “Destination IP address” and “Inverse” (all IP addresses except that specified). Please note that you should specify only IP addresses for NAT traffic, since UserGate NAT does not work with domain names.
