Any way I can do > this No. Sorry for the short answer, but intercepting and filtering https-communication is not possible with pfsense (nor is it with most commercial software). It is very difficult to lock down a network in such a way that no "undesired" packet leaves it. There is for example software that will create a tunnel through your firewall just by DNS - it will be slow, but it will be enough to remote-control a workstation and transfer files. It's professional pen-testers favorite tool to stump their clients... _______________________________________________ List mailing list List@lists.pfsense.org http://lists.pfsense.org/mailman/listinfo/list
