Conditional and dynamic firewalling

[tobiascapin]

Hello, I would like to know if it is possibile to set pfsense with some dynamic rules to allow or block some connections.
For dynamic rules I mean some external function using source ip address and destination ip, in my case I would like to store in a Mysql database a table of allowed destination ip addresses and a table of known internal ip source.  This is very similiar what I did with a squid proxy, but is it possibile to control pfsense firewall in this custom way?

Thanks
