Bridge lan+opt brakes without lan cable connected



  • Hi everybody,

    I'm setting up a pfsense pc, but I'm facing a problem that jim describes pretty well in the mailing list

    http://www.mail-archive.com/support@pfsense.com/msg08767.html

    In conclusion my observation regarding DHCP on the wireless interface is:

    !!!  When ath0 aka OPT1 and LAN interface are bridged,                    !!!
    !!!  pfsense will not offer DHCP address on the wireless interface if…  !!!
    !!!  the LAN interface is in down state, or otherwise not connected.      !!!
    !!!  because the bridge is broken and there is no connectivity between    !!!
    !!!  the 2 interfaces.                                                    !!!

    is there someway to fix this?

    thanks in advance,
    regards,

    Scroll down to the pinouts for the loopback plug. I use these all the time to verify interface ordering on boxes and such.



  • Is a loopback plug (and FW rules) the only solution when bridging OPT (Wireless) with LAN to get traffic between the interfaces?
    Connecting a switch to the LAN interface should also work, shouldn't it?

    Otherwise using a separate subnet for OPT with it's own DHCP server and use routing (and FW rules) between the two interfaces must be a better solution…

    Yes this works as well.
    However, the idea of a loopback connector is that you DON'T need an additional switch.

    Otherwise using a separate subnet for OPT with it's own DHCP server and use routing (and FW rules) between the two interfaces must be a better solution…

    This raises the question: why do you want to use bridging in the first place when you dont want to connect one of the interfaces?

    Because the gateway will be delivered to a client, so currently he will not use PCs with cable, but nobody knows what will happen in the future, so I want a machine ready to be used with a switch, just plug and use :)

    Thanks to everybody for the comments ;), the loopback jack is cool.
