Can't open webpage which url is of same domain as our LAN

  • Greetings.
    Let's suppose our domain is
    We have a pfSense 1.2.3 running and set up for that domain,
    Now we also have a webpage hosted somewhere on the internet which opens with
    We can't open such webpage behind pfSense but using a gsm/3g usb pendrive (not behind pfSense) we can easily open the webpage.

    Thanks in advance :)

  • Hi there,
    I'm posting because with the help of the guys down at #pfsense irc channel, i have fixed the issue.

    It started working right away.
