Comcast SMC Single IP Block



  • 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!
