Sometimes it’s necessary to whitelist an IP address so it can get past the mod_security filters. This is a great feature in case you want to open the filters for one visitor while leaving the security features in place.
Open the mod_security whitelist file:
vi /usr/local/apache/conf/modsec2/whitelist.conf
Code:
SecRule REMOTE_ADDR "^111.222.333.444" phase:1,nolog,allow,ctl:ruleEngine=off
Where 111.222.333.444 would be replaced with the IP address you wish to whitelist.
