Hello Guys
I decided to put a pfsense ( Squid+squidguard+snort)inmynetwork, i tired it on a virtual lab and everything is ok as far as filtering/ cache / alerts are concerned, but i have to say that there are lot of options i don't get but anyway i'm doing researches ( videos, forums...) now i want to prepare the deployement of pfsense in productionenvironement, so i prepared an old machine and installed Pfsense on it, now i don't get some points, as you can see in the picture i have 2 sites A & B we already have a firewall ( Cisco ASA ) in both sites, site B gets internet from site A ( the 2 sites are linked with a fiber link managed by our ISP...) could you please give me a hand on this particular case, the best postion to put pfsense ( before or after firewall ) the configuration of interfaces and gateway, fyi i can't change my sites...
