Actiontec 701 Port Forwarding

Is there a firewall running on the system you are using?

reply to dumberdrummer
Yes. I've tried it with it down and with it up and configured to allow those ports.

reply to dumberdrummer
I don't have it in front of me but there are 2 places to add for port forwarding in the advanced configuration, make sure those are set.

Out the 100Base-T, through the router, down the T1's, over the leased line, off the bridge, past the firewall... nothing but Net.

reply to dumberdrummer
All settings are correct in both port forwarding and advanced port forwarding.

reply to dumberdrummer
Try it without setting the machine in the DMZ, that is how mine is setup, I forward to the IP, but I don't put it in the DMZ.

reply to dumberdrummer
No dice.

I'm now on a 701WG. The first modem I had was a 1524. It had hangups with port forwarding. I never got a connection through from the outside unless I did DMZ. Nothing. Zip Zilch Nada. When it had the infamous critical failure with 100b channel and Qwest replaced it, I became happy very quickly.... >8)

I suspect its a bum chip on the Actiontec products. Try an RMA.

reply to dumberdrummer
Alright I will do that. Thank you both.

reply to RevMortis

this is my problem as well.

i log into the modem
1) Setup / Configuration
2) Advanced Setup
3) Begin Advanced Setup
4) Port Forwarding.

i fill out
IP Port Range Protocol IP Address
#### to #### udp/tcp Internal IP#

Yet it does not forward. so i click advanced.
And i fill out

Remote IP Port Range Remote IP Address
#### #### anyIP

Using the above #### as the same port number, [I only want 1 port forwarded], Why would there be no connectivity in the forwarding?

thanks

You don't want the advanced forwarding, so don't go to that page. Have you clicked "save and restart" after entering the port forwarding information? Did you check to make sure that the port forwarding was still showing up in the "List of Forwarded Ports"?

ok, so i'll remove the advanced information. and yes the basic information was still showing in "List of Forwarded Ports".

What kind of machine are you forwarding the port to? If its Windows XP, do you have Windows Firewall enabled (its on by default starting with SP2). You need to open the port in the Windows Firewall also.

You can check to see whether or not the port is being forwarded by the modem, but it's a little involved. Do you know how to telnet into the modem? If so, do you know how to capture (cut and paste for example) output for commands you type in? I'd like to see the output from typing "iptables -v -L" and "iptables -t nat -v -L". If you don't know how to do this, here are some more specific instructions for windows:

1) Start a cmd prompt window by clicking on "run" from the start menu. Then type "cmd" in the box and click OK.

2) Type "telnet 192.168.0.1" (use the internal IP address of your modem). Login using user name "admin" and password "admin" (the password will be different if you've changed the web admin password).

3) Then type "iptables -v -L" and then type "iptables -t nat -v -L" (hitting return after each command).

Now you need to cut and paste the output from the cmd prompt window. To do this:

1) Right Click on the title bar and click on properties. On the options tab make sure that "Insert Mode" is checked and "Quick Edit Mode" is not checked under "Edit Options".

2) Scroll back the cmd prompt window using the scroll bar until you can see the start of where the iptables output begins. Right click within the window and click on "Mark". Then left click and select the text starting at the first character and dragging down to the bottom right. Holding the mouse near the bottom of the window will cause the window to scroll automatically down to the bottom so you can select all the text in one operation.

3) The text should all be inverted now (by default it will be black text on white background). Hit return within the window and the text will no longer be selected but it will now be in the windows copy buffer.

4) start notepad and click on "paste" under the "edit" menu bar. Save the file.

5) Attach the file here so that we can hopefully diagnose the problem.

It would also be helpful to know 1) the internal IP address of your modem (by default it's 192.168.0.1), 2) the internal address of the machine you are trying to forward the port to, and 3) the port number you are trying to forward.

One of the other topics reminded me that there is also a "firewall" configuration option. Make sure that that is set to "off". You should only use the other settings if you have a block of static IPs that are forwarded to other machines. Turning this on can interfere with port forwarding.

They really shouldn't have called that setting "off". It should be labeled "NAT only" or something like that. "Off" makes it sound like you have no protection, which is completely wrong. Since most people have only private NAT'ed IP's behind the router ALL ports are blocked by default by the very nature of NAT. You have to explicitly forward ports for any inbound connections to work.

I go here »www.canyouseeme.org/ whenever I setup port forwarding to see if it's working or not.

Visit »www.spazmatic.net for more DSL information.

I'm in exactly the same boat. I've been fighting with port forwarding not working on multiple Actiontec modems all day at various locations. That link »www.canyouseeme.org/ would have been very helpful. I've narrowed the problem down to the Actiontec routers themselves. There has gotta be something I'm doing wrong but I've tried all the suggestions above to no avail. I'll be interested to hear the results on the iptables... If I can be of any assistance in tracking this issue down, by all means please let me know as I have about 3-4 Actiontec DSL modems I may just replace over this if the issue cannot be resolved.

Perhaps there is a common configuration problem that people are getting wrong. So, rather than try to go back and forth trying to figure it out, how about you send me your entire configuration and I'll figure out what you are doing wrong?

Here's how you can do this:

1) First, make sure you are running the latest Actiontec firmware. To check the version click on "status" from the Actiontec main page. Make sure the Firmware version is:

QW04-3.60.2.0.6.3-GT701-WG

If not, please upgrade your firmware. This most likely will not fix your problem, but your firmware needs to be compatible with mine, otherwise the rest of these instructions won't work. Go to this web page to get the latest firmware:

»www.qwest.com/dslhelp/modems/gt7···firmware

2. From the main menu click on "Setup/Configuration". Then click on "Alternate Setup". Record your username and password in case you don't have it written anywhere else. Now change both the username and password to "XXXX". Click on "Save and Restart" at the bottom. THIS WILL BREAK YOUR CONNECTION. The whole purpose of this step is to obscure your username and password so that you won't be sending it to me or anyone else. You will restore the username and password later. Meanwhile your internet connection will be down.

3. telnet to your modem (You can use a command prompt window to do this by typing "cmd" in the run box from the Windows start menu). In the command prompt window type "telnet 192.168.0.1" (substitute the IP address of your modem if it is different).

4. Log into the modem with account "admin" and password "admin".

5. Type the following commands:

cat /dev/mtdblock/4 >/var/mtd4
thttpd -d /var -p 1080
exit

http://192.168.0.1:1080/mtd4
