    Hi,

    I have a Draytek Vigor 2500VG, over a DSL connection. (bridged over a
    modem)

    Here's my problem:

    I have numerous PCs (GNU/Linux and Windows) all with file shares
    enabled. Now, from within my LAN I can browse all file-shares perfectly.
    The same cant be said from my wifi clients..

    From a wifi PC I can browse my network shares, connect fine etc.
    However, the moment any LAN based client tries to access a share on my
    wi-fi laptop nothing happens. The request just times out. What on
    earth is stopping my wifi clients from having their file shares blocked
    to anyone within the LAN?

    There are no local firewall(s) enabled on my client PCs, ideally i need
    to try another router to see if this is the cause of the problem! In
    addition to this, the moment I plug an ethernet cable into one of my wi-
    fi clients, my file sharing to the laptop (the wifi machine) works
    perfectly! So, it's not a configuration problem.

    I've run ethereal on the connection and it would appear that the packet
    is coming back from the laptop, albeit with a bad checksum (this is
    normal though), but no connection is granted. telnet <wifi laptop> 445
    just times out. Whereas if I plug in an ethernet cable and do 'telnet
    <ether laptop> 445' i get connected!

    Just what is going on?

    Anyone have any ideas?

    Cheers,
    Chris

    Are the LAN and WiFi the same network? I can imagine this would
    cause the problem you describe as several of the systems will
    have multiple NICs on the same network, and will likely only
    use one of them for routing. Different OS's behave in different
    ways in such wierd setups.

    If you really want multiple networks with multiple routes between
    the networks to work transparantly, you're probably going to have
    to run a proper routing protocol on the networks.

    Hi, appreciate your reply.

    They are on the same network, yes. 192.168.2.0/16

    All good points, and I can see where you're coming from - see my below
    post.

    Would RIP2 suffice? I ran this on my Netgear, but i can't appear to
    find it on my draytek. If RIP2 needs implementing then I can take this
    up with Draytek. At least now I know what is preventing my setup from
    working correctly!

    I'll have to grab a debian wifi laptop from work on monday and see how
    that works within my (W)LAN. Do you have any suggestions re the routing
    protocol?

    Thansk again,
    Chris

    I have similar problems using a 3Com wireless router. I have a wirelessly
    connected laptop which sometimes refuses to talk to wired PCs and vice
    versa. When this happens, if I ping the wireless m/c from a wired one, and
    vice versa, this usually gets them talking again.

    I have no problems communicating between WLAN > LAN. I can connect to
    EVERY open port, BAR 445! It's something on the router, I swear. Why
    would every port work fine from laptop (Wlan) to PC (eth lan) bar 445?
    I know it sounds like a local firewall, but it isn't. Windows Firewall
    is very much disabled, and there are no problems with file-sharing when
    the laptop uses ethernet

    Try having a sniff with Ethereal [on windows and linux] and see what's going
    on.
