Blacklisting & whitelisting clients using a source IP or source IP range You can define which source IP addresses are trusted clients, undetermined, or distrusted. Go to the IPS sensor -> Add signatures (under IPS signatures). Due to this, new options appear periodically. Once it expires, the IP address is removed from the wildcard FQDN object until another query is made. Keep in mind that if you black list or white list an individual source IP, it may therefore inadvertently affect other clients that share the same IP.

Bob - self proclaimed posting junkie!See my Fortigate related scripts at: http://fortigate.camerabob.com, Created on the HTTP status code. Use the first IP address you created in the prerequisites as the public IP for the firewall. Average bandwidth per participant for large organizations. The FortiGate will keep the IP addresses in the FQDN object table as long as the DNS entry itself has not expired. Data about dangerous clients derives from many sources around the globe, including: From these sources, Fortinet compiles a reputation for each public IP address. Configure GEO-IP address objects for the Countries to connect to the SSL-VPN. By default, FortiWeb scans the IP addresses in the X-Forwarded-For header at the HTTP layer.
