Dual WAN with two external and one internal network card?



  • Hi everybody,

    This is my network diagram:

    ADSL line 1 –--- External network card
    ADSL line 2 ----- Internal network card
                            External network card ---- Switch ----- LAN

    Can I config load balancing with above condition?

    My situation is:
    1. With two external network card, pfsense detect to: rl0 and rl1. I assigned rl0 to LAN, rl1 to WAN, and what will I enter for OPT1 (WAN2).
    2. I assigned 192.168.0.5/24 to LAN IP, but from a computer in LAN, I can't connect to http://192.168.0.5, and I get bellow error when ping:

    Destination Host Unreachable

    Thanks in advance.



    1. If there is no third interface listed you onboard noc is probably not supported by freebsd. Maybe add another realtek. They are cheap  ;)

    2. Make sure you are connected to the right interface. In case you are hitting the WAN interface you will be blocked by default. Also note that you probably need a crossovercable in case you are connecting a client directly to the LAN nic with no switch in between.

    Thanks for reply. But my computer has only two PCI slots. Can you give me a solution?

    I connected to right interface and I have a switch between pfSense and LAN.



    1. There are multiport NICs available. They are usually a bit more expensive though. Another option is to get a small vlanswitch like the hp procurve 1800-8g. Then you can easily trunk multiple vlans to the switch and break them out to dedicated switchports to get multiple interfaces.

    2. Make sure your client's IP configuration is matching the pfSense's subnet. If nothing helps try restarting with a factory default config and check if you can access 192.168.1.1.

    I am sorry for this question:

    I have configured various HP procurve switches; I know what are VLNs and trucking and how to configure it on HP procurve switch.
    Now, on configuring PFSense, I saw the fallowing message:

    If you do not have at least two REAL network interface cards
            or one interface with multiple VLANs then pfSense WILL NOT
            function correctly.

    My question is: can anyone point me to directly to one or more brands and models of network interface cards with multiple VLANs, working and tested with pfSense?

    Which is the better?

    Thanks in advance.
