pfsense not in the frontier
Is it possible to put pfsense in a network, and it is securing anyother machine in the same network it is ?
In a hipotetical network (192.168.1.0/24) we have 3 machines: pfsense (WAN add -> 192.168.1.1), pc_A(192.168.1.2), and pc_B (192.168.1.3). With this configuration, pfsense can provide security (filtiring, blocking, etc) to pc_A and pc_B ?
Not unless the L2 connection between pcA and pcB went through a bridge on pfsense.
How many interfaces does this pfsense box have?
It has 6 interfaces. But i am testing several possibilities with pfsense.
If you need to filter pcA and pcB, then you should normally put them on different networks.
There is little reason to but devices on the same network if your wanting to firewall traffic between them. If a box is on a hostile network, ie you want to put it behind a firewall from stuff on its own network then this is when host firewall becomes handy..
Or you isolate the boxes via your switch.. Like say with private vlans. Or if wireless clients would use client isolation on your AP.
As always, u r very helpful.
