we have somevservers in a datacenter. at the moment we dont have a physical firewall in place.
We have 2 reduntant uplinks (each from a core router) connected to 2 redundant switches. so each uplink is connected to each switch and the switches themselves are connected to eachother.
we want a physical firewall between the uplinks and the switches.
what is the best way to do this and which type of firewall can we use for this. And will there be a decrease of network performance?
thanks in advance for the help.
