I read that I should install Squid before SquidGuard. But what about adding LightSquid in the mix? Not sure if I really need all 3 but let's say that I do. So in what order of installation?
pfSense 2.3-RELEASE (amd64)
DELL Optiplex GX620 Pentium D CPU 3.40GHz, 240GB SSD, 4GB RAM
Went ahead to install Squid, SquidGuard and LightSquid in that order. Seems to work ok.
