      Hi

      I am new to pfsense so I am still finding my way around but I have a question as I have seen conflicting advice around multiple WAN set up.

      I have a /30 IP address range from my ISP, in order to access them all I have to configure the provided router in "bridge mode" so all it affectivly does is act as a modem and presents my 4 IP's to any device next in line. When in bridge mode I lose the firewall and the wireless from the modem hense the interest in pfsense.

      I have loaded pfsense on to a little ShuttleX PC I got from ebay and it boots up OK and I can get to the configuration pages. The install worked first time and detected the two NIC ports, well impressed ! I have configured the built in NIC as the WAN side and an added second NIC (a 1gig NIC) as the LAN side, that will connect to my Netgear prosmart 24 port switch.

      All my other devices will then connect to this switch, eventually I want to look at VLANS to seperate out the XBox and Wii, a DMZ with a server but lets get the basics working first.

      Taking things step by step so my old brain can get this correct.

      Can you experienced guys confirm that in order to see my 4 IP addresses on the WAN side I need to configure 1 of them as the WAN IP as normal and then add the other 3 as aliases to the WAN  or are they all aliased ?

      Simple question but advise would be received with thanks.

        Just a question - why would you need all 4 addresses? If your single port off the firewall will handle ALL traffic to the inside lan - is there a need to worry about the other 3 addresses? Or are you trying to squeeze more out of the pipe that you have? You only have one amount of bandwidth coming in so I am trying to understand why you would even worry about your /30 subnet?

        Best Regards;
