PFSence with Enterasys L3 switch
Currently I do not a have firewall on my development network but interested in trying out PFSence.
My concern is that my ISP gives me 5 static IPs (66.118.XX.120/29) of which I want to be able to use all of them as I need to. 121 is my modem so 122 thru 126 is mine.
From previous attempts with PFSence, I remember it tries to act as a router & firewall.
So my question is how to setup my connection between the modem to PFSence to my layer3 switch so as to maintain the ability to use all of my IPs.
you can use IP aliases on pfsense to have all of your IPs as WAN interfaces
pfsense is a firewall, do you not want to NAT your traffic at all?
You could set it up as a transparent firewall, WAN and LAN bridged, but you would need to add a third interface for management. If you didn't want to use any of your public IPs for that it would have to be in a new private subnet that you have access to in some other way. Without a public interface pfSense would be unable to check for updates or monitor the connections at all. I've never tried to do this.
I am not sure about the NAT situation as of yet since the Entrasys L3 switch is a new device and IOS to me and it also has some awesome NAC software controls.
Initially I just want PFSence to function as a firewall between my internal & external networks.
With the L3 switch bare to the internet the Chinese IP's have been pounding me relentlessly. Thank goodness I use 24 character passwords!!!
