Port forwarding on Conexant 4 port adsl router

Discussion in 'Broadband' started by Graham Russell, Oct 17, 2003.

  1. I've been playing for hours and I can't get port forwarding to work on my
    Conexant (Dabs value) 4 port adsl modem/router.

    The documentation I've read implies it works and with the latest firmware
    version from Amigo's web site (CA6XR-GN.0924.00T)
    the gui has all the right controls to set it up. I've mapped the ports on
    the Virtual Server page to the local IP address.

    I'm trying to enable web and telnet traffic into a local Unix server. From
    the LAN I'm able to access both services OK, but if I use the public WAN
    address it appears that the router is not forwarding the traffic onto the
    LAN.

    Has anyone with this router managed to get port forwarding to work?

    Thanks,

    Graham.

    You know you won't be able to access your lan via the internet from
    behind your router unless you use a proxy server , or alternatively use
    a dial-up modem.

    Does SGI and REX mean anything?

  3. Wow, they certainly do. I've left the router with virtual server turned off
    and dmz pointing at the internal server.

    I'm a bit new to this advanced networking stuff. Any pointers to setting up
    the proxy server you mentioned? You've obviously managed to get into my
    router externally - how did you do this? telnet? ftp?

    Graham.

    Turn off all the servers in the Misc Configuration menu and save the
    settings. Change your admin passwords as well.

    Hi Graham

    If its the same as the origo you will need to do a power down /up
    after saving/rebooting, to check it use http://www.guardster.com/ to
    check its working. I had a similar trouble till I did the above.

    I just typed http://nnn.nnn.nnn.nnn into my browser bar - I got the
    address from the headers on your post. I think you've got the port
    forwarding working ok, but you need to use a proxy to be able to test it
    from your network - to be able to go out on the internet and back again.
    Someone else mentioned http://www.guardster.com/ or you could use a
    different account (like I did).

  7. Has anyone with this router managed to get port forwarding to work?

    I have!

    See this site for setup info if you haven't already:
    http://www.cazart.plus.com/conexant/

    Having done the setup, I got the port forwarding to work via the Virtual
    Server page of the config. The only thing I need port forwarding for is so
    that DCC will work on IRC. And it does, after I put the correct ports onto
    the Virtual Server page.

    Hope that helps......

    So...
    How is port forwarding set on the Virtual Server page?

    Here is my guess, (but I'd appreciate confirmation before I destroy my
    connection!).

    ID Public Port Private Port Port Type Host IP Address
    1 6881 6881 TCP 10.0.0.8
    2 6882 6882 TCP 10.0.0.8
    etc.

    Is this anywhere close to being right?

    Any help most gratefully received.

    Dunno what you are trying to do, but it is probably right. Just
    remember that you have to save the changes which reboots the router so
    they take effect.

    To satisfy your curiosity (spelling??), I've started using BitTorrent
    and port forwarding has been recommended if you're behind a router.

    I'll wait until the curent downloads are completed before I try it.

    To: Jocelyn
    Does the above look about right to you (in order to pert forward)?

    Let me know if it makes any difference. I use BT behind NAT without
    port forwarding and it seems to be working just fine.

  12. Well, I am not an expert... I had help when I did mine :)

    But I *can* tell you two things.

    1. Mine says this:

    ID Public Port Private Port Port Type Host IP Address
    1 32768 32768 TCP 10.0.0.14

    (32768 is the port on which I do DCC via IRC)

    (Apparently 10.0.0.14 is the "public WAN IP address" of my airport (wireless)
    base station. I put that in the VS settings because I was told to. The only
    link I can see with any other part of the router config is on the LAN config
    page, where it says IP address (of the router, I think) = 10.0.0.2, DHCP
    server is ON (contrary to what that website says), DHCP address pool
    selection = user defined, start address = 10.0.0.3, end address = 10.0.0.14)

    (Again I can't remember why these numbers are there - I was just following
    instructions from someone who knew far more about it than me!)



    2. I run BitTorrent through this router (and behind the Mac OS X firewall),
    but I have *not* enabled the BitTorrent ports (6881 etc.) on the Virtual
    Server config page. This is because BitTorrent worked before it occurred to
    me it might not :)


    Hope this helps. If not, ask again and I'll ask my networking guru (who is
    helpfully offline right now!)

    For those still interested, at first I wasn't going to port forward, due
    to Jocelyn and Andrew's eminently sensible remarks (and my own innate
    cowardice).

    But then I had a torrent that was sluggish if not entirely dead.
    So I did the port forwarding, and lo, it sprang to life!

    I can now see why.

    I use Azureus as a Bittorrent client, which shows you lots of the inner
    workings, which is nice.

    One thing is shows is whether you have connected to them, which is
    local, or whether they have connected to you, which is remote.

    Before port forwarding, all my connections were local, (and were few, if
    not entirely, non-existent on this particular torrent).

    After port forwarding, most of my connections were remote, as now they
    could get through my router. Hurrah!

    This is as predicted in the Bittorrent FAQ at
    http://www.dessent.net/btfaq/
    (tho' currently offline)

    Another case of RTFM...

    Thanks for letting us know. Its strange you need to do that though, I
    use the normal Bittorent client via NAT and it is currently
    downloading the Silent Hill 3 demo just fine at 17K download and 27K
    upload. I have had downloads faster than that before now too. Maybe
    its an issue with the client that you use.

  15. 2. I run BitTorrent through this router (and behind the Mac OS X
    Well, I read this, and thought "good grief, you mean I could have had faster
    connections all this time?!?" So I set up the port forwarding, mentally
    composing my "I am SO stupid!" post.

    Sadly it has made no difference whatsoever - in fact, if anything, the
    transfers are SLOWER. Although that is undoubtedly just down to the
    constantly changing BitTorrent environment.

    Oh well :)
