No internet access



  • Hi guys,

    I just installed my first pfsense server (release 2.1).

    It´s a old pc (DFI Lanparty SLI-DR with dual gigabit lan, Opteron dual core e 2 GB RAM).

    Here is my problem: I can´t access internet.

    Wan interface connected to cable modem with IP addressed from my ISP (DHCP) = OK
    Lan interface connected to my switch (DHCP working well). = OK

    Through the web interface, I configured the DNS (8.8.8.8 and 8.8.4.4) servers. And also I enabled the option to allow DNS from ISP's.

    I tested a few things like: ping test (www.google.com) through the WAN interface successfully, but testing again via the LAN interface does not work.

    Make sure that you haven't defined a GW for the LAN interface (you need only the WAN GW)



  • Disconnect the WAN cable from the PFSENSE, to identify which NIC is LAN and WAN,
    also check if you created the FW rules to allow the internet from the LAN

    Ok, Done! But still not working !



  • @Jamerson:

    I already did that! (identify Lan and Wan interfaces) and all interfaces are working well. I did the ping test (Diagnostics>Ping) and selected:
    Host = www.google.com
    IP Protocol: IPv4
    Source Address=WAN
    Count=3
    This works !!!

    But when i try Source Address = LAN, doesn't work! All packages loss.

    About the rules, I dont have any in place. Do you know how I create this rule?

    thanks!!



  • Have you setup a default firewall rule to allow all from LAN to WAN, this caught me out originally.



  • like James says it probably a firewall rules,
    can you post a screenshot of your firewall rules ? WAN and LAN ?



  • Guys,

    Many thanks for the help! Your answers put me in the right way and I found some information on this forum about rules.

    The solution was that! I had to create some rules. I don´t know if I´m doing the right thing.

    Here was necessary to create about 8 rules. 1 for Http, 1 for https, 1 for DNS, 1 for ftp ….. and so on.

    best regards



  • You can just create one rule under LAN firewall rules, allow any to WAN to get you up and running.

    Could you show me how I create a single rule?

    Its like subnet = lan any to wan any!?
