PFSENSE and Comacst



  • I have comcast and pfsense 1.2.3. I have setup manual DNS's IP in General SETUP. I have also tried to assign DNS in DHCP but recently unchecked that options.

    As of now I am able to ping www.yahoo.com deirectly from pfsense (that is from console by F8 in shell) that means that pfsense is connected to internet.

    However, when I use any host (desktop) and it gets IP from pfsense (DHCP) I can't open any www also pinging in cmd shows DNS problem.

    IPCONFIG shows DNS of pfsense' IP so it is ok.

    What could be the problem. I have tried many options and none of them works.

    Thank You



  • WAN IP config is set to DHCP besides statis DNS



  • Do you have the DNS Forwarder service started.

    Cheers.



  • Yes I have it enabled.

    If I have Allow DNS server list to be overridden by DHCP/PPP on WAN enabled and DNS servers are filled out do I have to retype DNS in DHCP?
    WAN has it's own DNSes but I wan to use other because they are much faster. So I have to override them by typing DNS in GENERAL and enable  Allow DNS server list to be overridden by DHCP/PPP options?

    This is kind of confusing.

    Thank You



  • It sound as if you want to DISALLOW DNS server list to be overridden by DHCP/PPP on WAN so pfSense will use the DNS servers you specified rather than the DNS servers chosen by your ISP. If you are running DNS forwarder you don't need to specify DNS servers in DHCP - systems downstream of pfSense will use pfSense as their DNS and the DNS forwarder will use the DNS servers you have specified when it needs to use an external DNS.
