    I succesfully installed the Ethereal on a RH9. I would like to capture the
    packets for the whole network , not just those coming and going to my eth1.
    This RH9 is a desktop in the network and "not used as a router", then I'm
    not sure if it's possible to sniff into the routers packets. The router is a
    Linksys Wireless-B Broadband Router BEFW11S4.
    I think (not sure why) I'm capturing everything coming into the LAN but only
    those packets going out from my eth1. This means I get :

    192.168.1.100 <----> WAN

    but only

    LAN (192.168.1.xxx) <----- WAN

    and I would like to have from this desktop (I don't know how to do this on
    the Linksys)

    LAN (192.168.1.xxx) <-----> WAN

    in order to capture all the packets.

    My network map is something like this:

    INTERNET
               |
    Dinamic public IP (WAN)
      | CISCO 677*|
           10.0.0.1 (LAN)
                |
           10.0.0.2 (LAN?/Intenet?)
        | Linksys**|
        192.168.1.1 (LAN)
                |
                |---192.168.1.100 (RH9 w/Ethereal)
                |---192.168.1.101
                |---192.168.1.102
                |---192.168.1.nnn

    * DSL modem router using PPPoA
    ** router and wireless accespoint

    any clue to use the ethereal to capture in/out Linksys packets?
    Also I would like to have an advice if there is another way to configure
    this devices (DSL modem router/ Wireless router) referring to ip lan side
    numbering (10.0.0.1/10.0.0.2/192.168.1.1/192.168.1.nnn)

    Thanks in advance,

    Sergio
