Port forwarding has stopped working on my arris bgw210-700

I'll try restarting the bgw210 when i make each change. The router never got an IP assigned at anytime during the process. It is a brand new Asus N600, that I picked up for cheap to potentially use as an access point but never got around to it.

@h3lpPlz Thanks for all your help!

I said screw it and just ordered a ubiquiti USG. I'm tired of the games

I'm also having this issue - brand new customer, quite frustrated already.

Please add me to the response list once this has been resolved. 

@ATTcares please add me to the list of those to contact with a fix, or a new modem. 

I tried the suggestion of putting the gateway in IP Passthru with a router behind to do port forwarding.  I still cannot see my security cams outside the network.  

I've been having the same issue. I think I've got a temporary "fix". I noticed if there is a constant connection through the firewall, it won't break port forwarding. So want I've done is started a SSH connection using the external IP address port forwarded into a computer I have running on my network. I assume if you do something similar (contstant connection that uses port fowarding) it might work. So far port forwarding has been working for over 12 hours without an issues when it usually breaks within an hour or so. I really hope AT&T fixes this soon. 

i'm successful setting it to IP passthrough, using DHCP and supplying the MAC of my other router (found in the drop-down). I first turned off both wireless bands. once everything was done, i did a power cycle.

Just make sure you set the two routers to different addresses (192.168.0.1 and 192.168.1.1 for example).  then put the port forwarding in the downstream router.  i configured everything so all my old router settings were the same and everything works.

It appears you guys had a firmware update that broke port forwarding. Please helps me fix this or my security cameras are useless.

It appears your response is just over a month old; any progress?

My ports are now staying open,,,problem is solved at the moment with the most recent router firmware:

http://gateway.c01.sbcglobal.net/firmware/001E46/BGW210-700_1.7.14/

(1.7.14)     as of today,,,,

download file,

 go to router web page, (info found on router)

then,,,

i'm not a techie so i thought it was me,,,it wasn't

1.7.14 seems to have been pulled from the download server. I don't think its a fully baked / ready for release build. It has some odd things about it. You can't turn off all the firewall settings like before. A scan from GRC showed that the flood limits were still enforced with no way to disable it. Only about 1/4 of the firewall options were available. Parental controls I have no use for seem to have been added though. And under syslog the only log you can view is the firewall log, nothing else. Like I said, seems half-baked and not ready for release. It is nice to know that you can flash a older firmware which is what I did. I flashed back to 1.6.9 with no issue.

1.6.9 is the latest officially released version that people have received automatically/normally from AT&T. I'd suggest sticking with it since it fixes the port forwarding problem caused with earlier 1.6.x versions. Also AT&T pulled 1.7.14 from the update server, the link no longer works. 1.6.9 download still dose.

When will this be fixed?  I'm having this problem also!
