      Hi all,

      We have a Comcast SMC modem behind a SG-2440. The modem is bridged and the WAN interface is set to DHCP. Everything works fine but the IP changes sometimes and screws up some of our internal applications. We've recently purchased a single IP block from Comcast to keep our address static.

      This is the email from Comcast:
      Modem set in virtual bridge mode
      Start Address 96.91.xxx.xx1
      End Address 96.91.xxx.xx2 = gateway
      Subnet Mask: 255.255.255.252

      I've set the following settings on the PfSense:
      WAN - Set to static IPv4
      IPv4 Address: 96.91.xxx.xx1/30
      IPv4 Upstream Gateway: 96.91.xxx.xx2

      LAN - Set to static IPv4
      IPv4 Address: 10.1.10.1/16
      IPv4 Upstream Gateway: None

      Am I missing a step here? DNS or routing tables perhaps? I can't seem to ping google.com or 8.8.8.8.

      Thank you in advance!
