      I currently have pfSense running fine on my network, but I am looking to make a couple of changes. One of those changes is to add a 10g switch add a 10g NIC to my pfsense and move my TrueNAS server to 10g NIC.

      I've added the 10g NIC to my pfsense router and the question I have is, is there a way to add the second LAN and have it share IPs with the one that is already configured. If I set the switch in back of the existing switch I get an IP from the router and so does every other device I plug into that switch. Is there a way to enable that but have two switches connected directly to the router? If that is possible can someone point me in that direction.

        @vMAC If you have a 10ge switch and you want everything on the same network - just plug your 1ge switch into your 10ge one.

        If you want to run 2 networks then sure plug your 1ge switch into a pfsense port and give it a different network..

        Not sure what the point would be of plugging the 1ge switch into a pfsense port if you want everything on the same network.. Do you have over 10ge internet? Daisy chain the switches puts everything on the same network already.

        You could setup a bridge on pfsense - but that is never a good idea.

        Why exactly would you want to connect these 2 switches into 2 ports on pfsense if you want them to be on the same network anyway? Are you wanting to firewall between them? But have broadcast and multicast on both?

          I guess I didn't think about that. Daisy chain it pfsense -> 10g -> 1g?

          Best way to convert that just editing the config directly to swap the interfaces?

            @vMAC yeah your 10ge would just be your lan.

              Just as an ans, I have this setup - three sets of switches are connected to the three ports on pfSense; one serving WiFi, one HomeLan and third one for Storage but of cource, I didn't wanna have 'em all in the same physical network.

              In that way, I can manage these three services seperstely and family don't start yelling at me when I'm doing something on the Lan side or the files arer still availabe from my Storage over the WiFi or daughter can go back to her iMac when I'm updating the WiFi system (as long as pfSense is up and running) :)
