My boss wants to allow facebook, and this info helps a lot.
I've set up the IP4 rule in pfBlockerNG as presented earlier (thanks), but I'm not getting all pictures though.
I do have a couple of questions:
1) Are my changes supposed to be taking effect when I force update? or only when I reboot? (I seem to get different results at times)
2) Should I permit Outbound only? or Both?
3) Should I allow the IP6 range for facebook? see (http://bgp.he.net/search?search%5Bsearch%5D=facebook&commit=Search for list)
I have tried all the above, but still missing a lot of pictures.
facebook does work fine when i disable pfBlockerNG.
P.S. I've also turned on Alexa 1k whitelist…perhaps bumping that up would help? But at what cost?
