pf by content?
i was just wondering if its possible to have a pf rule to filter on text content
why? i have a dayz server that runs remotely, it seems every script kitten in the world is bent in injecting the database full of crap to cheat. as you cant run a public hive on a local machine and still be apart of the community my solution is to move the mysql database to a local machine. so i wanted to find some way to drop any request that has a #! or similar script id? not sure if its possible but tia |

No, pf cannot filter on text content. That would be what is called deep inspection.
If the script kiddies mess around with the webserver you would need an application firewall like mod_security See http://en.wikipedia.org/wiki/Firewall_%28computing%29 for information about the OSI levels a packet filter operates.
