Setting Up Defender DVR Cameras to Work With AT&T U-verse ARRIS NVG589 Modem

I recently got a new ARRIS NVG589 modem for my AT&T U-verse and had some problems getting my Defender DVR with Cameras to work on my mobile device. I finally got it to work so thought I would show how I have the ARRIS NVG589 modem setup.

First you want to bring the screen for the modem on your browser. In your browser’s address bar type in the IP address of your modem which mine is Next click on the Firewall tab as shown in item 1 above in Figure 1. You can click on the image for a larger view. You may be asked to enter the password for your modem at some point and the password can be found on the label on the bottom of your modem.

Next click on NAT/Gaming sub tab as shown in item 2 in Figure 1 above. Then once the page is display you want to click on Custom Services as show in item 3 in Figure 1 above.

Next you want to enter the Service Name in item 1 in Figure 2 above. This can be what ever you decide to name this service. Next enter the Global Port Range in item 2 in Figure 2 above. Here you want to enter 18004 in both boxes unless you change the setting in you Defender DVR then enter the port that you change it to.

For the Base Host Port you will enter the same 18004 port or the port that you change the setting in your Defender DVR. Leave the Protocol as TCP/UDP as shown in item 4 in Figure 2 above.

Now click on the Add push button as shown in item 5 in Figure 2 above. Your setting will be saved and will show up in the Service List at the top of this page. Next click on the Return to NAT/Gaming push button as shown as item 6 in Figure 2 above.

You will be returned to the NAT/Gaming page as shown in Figure 3 above. Now you want to select the Service that you just created as shown as item 1 in Figure 3 above. Next select the Defender IP Address in the Needed by Device drop down list as shown as item 2 in Figure 3 above. You may have to access your Defender Network settings to find out what IP address your Defender is using.

Finally click on the Add push button as shown as item 3 in Figure 3 above.

Next I repeated the procedure above and added port 9000 for the Defender.

I hope this will help someone to get their Defender DVR to work with the ARRIS NVG589 modem as I couldn’t find any good instructions on the internet doing a search.


  1. I just wanted to thank you so very much for your blog on the Defender and Uverse NVG589 modem for port forwarding. I was at the end of my rope trying to get it configured, and when I happened to come across your blog, I had it configured for my wifi and away from my wifi, ALL BECAUSE OF YOU!!!!!!!!!!!

    You are my hero, and I thank you sir. Also, Happy Belated Memorial Day. Thank you for your service as well. God Bless.

  2. You saved my life. Thanks so much for the instructions!

    Re Arris NVG589 Defender setup. I completed all the steps and went to canyouseeme website and both 18004 and 9000 show success. Before I close out the setup page is there a save button supposed to be beside the add button. Both of the applications show in Hosted Applications but in below in the SERVICE block they have a asterisk beside them and are at the top of the lists instead of in alphabetical order. Thanks for all the help.

    Thank you!

  7. Thank you!! Very concise, easy to follow instructions! One question though, I can only watch my cameras on data service when I am there. If I try to watch on WiFi (the same network that the cameras are running on) it won’t let me. I have to log off the WiFi first, on my phone. Any ideas on how to fix that, so that I don’t have to shut off WiFi and use up my data while I’m where the camera system is?

  8. I have the NVG599 and this article was very helpful. I set up the mentioned ports as given (18004, 9000, 5000), but it did not work until I set up port 5050 also. Great article.
