8/26    I get my DSL from SBC (which uses PPPoE), and when I connect the
        DSL modem directly to my freebsd machine it connects fine (using
        /usr/sbin/ppp). But when I go through a Linksys router, to
        share our DSL line with my other roommates, I can't connect
        anymore. Is there something special I have to configure on my
        machine to be able to connect? Thanks.
        \_ I imagine the Linksys router "hides" the PPPoE end of the DSL
           line, i.e., all your computer should care about is turning
           on the DHCP client (any PPPoE thing should be off).
                \_ How do I do that? (I'm a newbie still)
                   \_ I'm a FreeBSD newbie, but I imagine it's "turn off
                      /usr/sbin/ppp" and "turn on the DHCP client".  There
                      should be a FreeBSD FAQ on that.
        \_ 1. Make sure your router is actually doing PPPoE (ie, verify that
              your roommate can connect to the internet.)
           2. dmesg|more and look for your ethernet device, possibly xl0
              or something similar.  Edit /etc/rc.conf and replace any
              ifconfig_xl0 lines with ifconfig_xl0="auto", which will handle
              the dhcp client for you.
           3. If anything goes wrong, mail your friend who helped you set up
              your machine.
                \_ I actually just turned off ppp and then ran dhclient, and
                   everything worked out fine. (except that now I lost my
                   ability to host a webserver since I don't have a real IP
                   anymore).
                   \_ All routers like this I've seen allow you to route ports
                      or port ranges to a specific client behind it.  I run a
                      webserver behind one of these routers just fine.
        \_ My God, they let people like you on the net?  That's shockingly
           dangerous.  Do you make sure to respond to all spam and open all
           attachments from Tiffani?
                \_ My God, the did let me on the net! Are you shocked?

11/7    Need help on http proxy. After I VPN to work, I'd like to tunnel
        all the traffic to my machine. How do I setup my machine (Linux)
        as a proxy server so that my home computers can route through it?
        I'm asking because the site we're testing on requires that we
        come from the same IP. If I use VPN, the server will reject me
        based on the fact that it's a different IP than my work Linux.

8/5     It looks like my company has started blocking HTTPS tunneling.
        I used to do this by tunneling SSH through the HTTP/HTTPS proxy
        server, but this seems to have stopped working. Does anyone know
        how the implementation of tunneling detection works, and whether
        there are widely available implementations? We run a bunch of MS
        stuff, so I imagine we're running an MS proxy server or something.

        Cygwin is also installed if that helps any. Thanks

4/19    After installing Logitech wireless mouse, my friend cannot connect from
        his PC to his wireless broadband router via a USB wireless network
        device.  It said that it cannot obtain IP address from the router.  Even
        uninstalling the Logitech wireless mouse doesn't help.  Do you know how
        to fix the wireless LAN problem, so that his PC can obtain IP address
        again?

5/23    I have DSL through AT&T. The service was originally established
        through PacBell, transitioned to SBC, and now AT&T. I still have
        my original plan and never converted to a SBC Yahoo! (now AT&T
        Yahoo!) account. I noticed the price will be a lot cheaper if I
        do. Are there any drawbacks? I thought someone mentioned some
        negatives about the Yahoo! tie-in once upon a time.

2/18    My DSL modem's ip address is 192.168.0.1, my internal network
        behind my router is 10.0.0.x. Is there a way I can configure
        the router so I can access the DSL modem from my 10.0.0.x
        network directly without re-wiring? Static routes? I tried it
        but no much luck. I also tried changing my internal network to
        192.168.0.x, but still does not work. Thanks.

1/28    Just switched to Comcast from SBC and generally happy with it.  But
        can someone please explain to me why they are constantly pumping
        ARP traffic through the network?  It seems harmless, but I'm curious
        as I didn't see it with DSL.  It's a little disconcerting to see
        constant traffic on your router, even if ARPs are harmless from
        a bandwidth perspective, and it makes the WAN send/receive light

1/21    I am trying to setup a small network for my girlfriend's
        mom's company.  They just bought an accounting package
        which requires windows 2003 server.  And they want internet
        access from each computer.  How should the network be setuped?
        Would it be dumb to use static IP for each computer and a
        computer as internet gateway?

8/29    What's the difference between a hub, a switch and a router?  Thx.
        \_ AFAIK, probably be corrected by someone:
           hub: Allows communication on a LAN with bandwith shared amongs all
                the nodes on the hub and maxing out at the max line speed.
           switch: Allows communication on a LAN with bandwith greater than
                the max line speed (point to point)

6/2     I've been to many places and almost every place I go to have
        802.11b/g. However, almost all of them have protected access,
        which I presume they use because they don't want people stealing
        their bandwidth. So here is one idea I think will really
        revolutionize 802.11X... an option in the router that allows you to
        specify the percentage of unprotected bandwidth you are willing to
