Firewall

Through the firewall panel, it is possible to ban specific IPs to access your API. Fusio contains also a fail2ban logic to automatically ban specific IPs in case they have produced too many error responses.

Configuration​

Name​

The name of your firewall rule.

Type​

Whether to deny or allow the request.

IP​

The target IPv4 or IPv6.

Expire​

Optional a date at which the ban expires.

Fail2ban​

By default, Fusio contains a fail2ban logic to automatically ban specific IPs in case they have produced too many client error responses. In case a user tries a brute force attack on the authorization endpoint, we automatically ban the IP for 5 minutes in case the user has produced more than 32 error responses. You can adjust this behavior at the configuration.php file s.

'fusio_firewall_ignoreip'  => [],
'fusio_firewall_bantime'   => 'PT5M',
'fusio_firewall_findtime'  => 'PT2M',
'fusio_firewall_maxretry'  => 32,
'fusio_firewall_codes'     => [],

fusio_firewall_ignoreip​

Optional an array of trusted IPs which are excluded from the fail2ban logic, this means they never automatically get baned.

fusio_firewall_bantime​

The time window how long the IP should be banned.

fusio_firewall_findtime​

The time window in which we look for error responses.

fusio_firewall_maxretry​

The number of error responses which are allowed.

fusio_firewall_codes​

Optional a list of specific error codes which should be considered. In case you want to only handle i.e. 401 and 429 error codes you could use [401, 429] all other error codes like 400 are then ignored.
