Modem-Router port forwarding problem.

[Carlos Marcano]

Hello.

I have recently got a subscription to wireless (as in cellular) adsl
internet connection. My ISP (<www.cantv.net>) provided me with a
modem-
router from Axesstel, the AXW-D800. I have been using it with DHCP and
NAT enabled and so far the internet connection is up and running on my
dual boot WIN XP Pro / Ubuntu 7.10 machine.

The problem is that whenever I try to use any of the bittorrent
clients I keep getting NAT problem messages and they complain about
the required TCP and UDP ports being closed. I have found and followed
info on the net with no succes. One of the more illustrative sites on
this topic is <www.portforward.com>. It even has very detailed
instructions with the actual images from my modem-router web admin
utility at <http://www.portforward.com/english/routers/
port_forwarding/
Axess-Tel/CDMA-1XEV-DO/Azureus.htm>
regarding of portforwarding using the bittorrent client Azureus as an
example.

I have taken these instructions by the letter and I have had no
succes at all. I hope anyone could spare some help on this very
annoying issue.

On other related matter I have also bought a wirelles router (it will
arrive soon) to share my connection in my house with a couple of
laptops. It is a D-Link DIR-655 Xtreme N Gigabit Router. I would like
to know if it is possible to omit the DHCP and NAT options on my
modem-
router and let the wirelles one implement these. I was thinking on
bypassing the IP assigned from my ISP to the modem-router and "put" it
to the wireless router so it implements the DHCP and NAT. I want to do
this because I think that the modem-router is failling in the
portforwarding issue so I would like to try this option with the
router. Does this make sense at all?

Thanks in advance for your time and help,

Regards,

No such thing. ADSL only works over telephone wires. Cellular data is
totally different. Likewise Wi-Fi.

Those details are helpful -- thanks. The Axesstel AXW-D800 is a
CDMA2000 EV-DO Wireless Broadband Modem.

Your service provider may be blocking BitTorrent ports. Many service
providers see filesharing as detrimental to their networks.

I doubt it, but try turning off DHCP and NAT first with just your
computer.

If that works, then get a wireless router.

If not, and if the AXW-D800 can handle multiple clients, then a wireless
access point (or wireless router configured that way) would probably be
better.

You are right. Thanks for the info.

I have thought in that but after doing research it looks like this is
not the case. I have also tried using lots of other random ports for
the bittorrent clients with no luck at all.
