Netblock Settings

Temp to Perm Settings

Temp to perm blocking - LF_PERMBLOCK
Enable temporary to permanent IP blocking. This will permanently block IP addresses that have been temporarily blocked more than LF_PERMBLOCK_COUNT times in the last LF_PERMBLOCK_INTERVAL seconds.
Default: 1 Range: 0-1

Permanent block interval - LF_PERMBLOCK_INTERVAL
The interval in seconds before triggering a Permanent block. LF_PERMBLOCK_INTERVAL needs to be at least LF_PERMBLOCK_COUNT multiplied by the longest temporary time setting (TTL) for blocked IPs, to be effective.
Default: 86400 Range: 3600-604800

Permanent block count - LF_PERMBLOCK_COUNT
The number of times before triggering a Permanent block.
Default: 4 Range: 1-20

Netblock Settings

Netblock blocking - LF_NETBLOCK
Permanently block IPs by network class. Permanently block classes of IP address where individual IP addresses within the same class LF_NETBLOCK_CLASS have already been blocked more than LF_NETBLOCK_COUNT times in the last LF_NETBLOCK_INTERVAL seconds. This can help blocking DDOS attacks launched from within the same network class.
Default: 0 Range: 0-1

Netblock interval - LF_NETBLOCK_INTERVAL
The interval in seconds before triggering a Permanent block by network class.
Default: 86400 Range: 3600-604800

Netblock class - LF_NETBLOCK_CLASS
Care and consideration is required when blocking network classes A or B.
Default: C Range: A|B|C

Netblock blocking IPv6 - LF_NETBLOCK_IPV6
Enable IPv6 netblock blocking. Valid settings for LF_NETBLOCK_IPV6 are "/64", "/56", "/48", "/32" and "/24". Great care should be taken with IPV6 netblock ranges due to the large number of addresses involved.
Default: empty
