{0}IP Security{1} is used to restrict login to the portal from all IP addresses except certain addresses. You can set the allowed IP addresses using either exact IP addresses in the IPv4 format (#.#.#.#, where # is a numeric value from 0 to 255) or IP range (in the #.#.#.#-#.#.#.# format). The IP security does not work for portal owners, they can access the portal from any IP address.
