Please help Mobile phone connected to lan but no internet access



  • I recently configured pfsense as my firewall and router.
    I have the PPOE running on one NIC and DHCP on other NIC.
    Then I have an access point to provide my home with Wifi, all connected to same switch.
    All PC's and Laptop's are connecting fine and has internet connection through LAN or Wifi.

    But any mobile phone connected to the Wifi gets an IP from my DHCP and are able to ping my DHCP server, however i'm not able to ping any external sites. So my phones has IP's but no internet connection.

    This seems like a DNS error, and I have tried changing all DNS settings but no luck.

    Can anyone please help



  • Hi,

    Take a look at your phone.
    If all devices work, Wifi and LAN (cable), then your setup is ok.
    If the phone gets an IP from the DHCP server's pool,that great, but what was the DNS and Gateway ? These two make the upstream connection work.

    On pfSense, the DNS Resolver, with default settings works great, if not best.



  • Thank you for the reply.

    The phone gets the PfSense as gateway 192.168.1.254 and for the DNS's.
    But reading your reply made me think I'm running PfSense as a virtual machine, and the host has an static address for one NIC where its has an IP 291.168.1.10 and then my virtual machine (PfSense) also gets its connection over the same NIC 192.168.1.254. Could this be the problem? should I insert another NIC and assign it to PfSense alone for LAN?

  • No, that's a normal setup for virtualized firewalls.

    To screen out DNS issues try typing a known IP address in the phones web browser. e.g. 98.138.219.231 for yahoo.com and if it loads.



  • Hi no even pinging 8.8.8.8 does not work

    But you can ping the pfSense interface address? Something's not right there then.

    Do you actually see the phones in the DHCP lease table?

    I'd try running a packet capture or at least checking the state table when pinging from the phones to see what's actually being sent.
