Might it be you are mixing some things up here?
pfSense is a full blown, enterprise grade router/firewall that runs on most any standard PC-based hardware.
It has a WebGUI for configuration but by no means is it a replacement GUI for your DSL router.
Given the feature set of this software and your statement that your "PLDT my web configuration is not so easy to use", chances are, that pfSense is overcharging your current capabilities. Expect a steep learning curve at least.
