I need help, I just got your service and I have been pulling my hair out on how in the world to get my router to work behind this modem/router. I have configured IP Passthrough and have now disabled the AT&T normal WiFi. I got it all working well for my home network. Issue I have now is, I cannot find a way to forward ports to allow connections thru putty, HTTP and VNC from outside the local network. I have the ports forwarded on my router, but using the public IP to get there doesn't work.
I feel like the Cascaded Router option is maybe where I need to go, but I cannot seem to get it to accept the numbers I am giving it.
I have been really upset about this setup, it has not been a good start for me and AT&T. I just left Charter but may consider moving back next year if I cannot get this resolved.

Cascaded Router is NOT the place you want to go.
Can you provide screenshots of your Passthrough page?
Can you confirm that your router shows that its external address is your public address?

Your images show up as "[image: image.jpg]". Did you e-mail your reply? You may need to come back to the forums and use the image tool.

I cannot figure out the image thing.
Allocation Mode - Passthrough
Default Server Internal Address - 192.168.1.1
Passthrough Mode Manual
Passthrough Fixed Mac Address - The routers MAC
Passthrough DHCP Lease - 10 Min
WAN Setup on Router
Connection Type - Static IP
WAN IP Address - 192.168.1.1
Subnet Mask - 255.255.255.0
Gateway - 192.168.1.254
Static DNS 1 0.0.0.0
Router IP Local IP Address - 192.168.0.1
Subnet Mask - 255.255.255.0
Gateway - 192.168.1.254
Local DNS 192.168.1.254
I wonder if the Gateway needs to be my Public IP?

Thank you, this did it! I had to then port what I needed thru the NAT/Gaming tab to allow it to go thru to Passthrough.
Only issue have right now is, it is saying that I cannot pass port 22, which is for SSH, because it conflicts with a reserved port (22). Any thoughts?

FYI: Found this after having same issue.
Google Chromecast 2nd Gen and Google Cast Apps totally kills AT&T U Verse network (affecting many users), Arris BGW210-700 Gateway router death by a 100,000 MDNS packets both wifi and wired connections droop forcing reboot to re-sync. The issuse has be ongoing since sometime November of 2017. I have had 5 AT&T techs come out to the house to no avail.
Note stability has improved over time but issue has not been fixed.
- I am in the Preview Program, Google Play Services beta.
So this morning I unplugged my ChromeCast, and the BGW210 network immediately crashes. Long story short I strongly suspect it's Google Apps that Cast, Google Home, YouTube etc. So I took both android Phones off the wifi network. Network stability has improved. I noticed connectivity would often drop whenever I would wake phone while connected to wifi BGW210 wifi radio may be buggy, as other AT&T users have noted, only to be compounded by Chromecast MDNS packets.
Think this is happening with all Google devices not just phones.

For full passthrough you need to not only enable the passthrough function in the gateway but also disable everything in the firewall advanced tab (or as much of it as it will allow). Also delete everything under the packet filter tab and nat/gaming.
Under passthrough mode make sure dhcps-fixed is selected and your down stream router's mac is defined as the target.
This will then pass the public ip down to the wan port of your router. This is where you open up any port forwards or other inbound access. Bear in mind certain ports are blocked by the att network - see this link http://about.att.com/sites/broadband/network .
Your downstream router should *NOT* be getting a 192.xx ip on its wan port. If it is, recheck the pass through settings in the gateway. You should be seeing your public ip (107.xxx or). WIth the 192.xx ip that means you have a double nat arrangement and the gateway is still doing filtering.
Note, since version 1.5.xxx firmware, dhcps-dynamic passthrough mode is broken and passes a 192.xx ip even to the first device to perform a dhcp request. Use fixed mode instead.
Finally, for security purposes I'd suggest using a certificate based authentication if you're going to allow remote ssh access. Have you considered setting up a vpn server for more flexibility in remote access?

Hi. I am having the exact same issue. I have setup BWG210 in IP Passthrough mode and turned off all other firewalls functions in BWG210. I can see my external IP address as the WAN IP in my ASUS RT-AC88U router. Port 443 amount others are forwarded. When I try to ping them using canyouseeme.org all the forwarded ports come back as failed. All other internet functions are working. Even my son's XBox which also requires forwarded ports is working fine with XBox Live. But fore some reason I cannot connect to web server running on my internal network from outside my network. Inside my network I can connect to server with no problem when using my external IP https://myipaddress. Spent 10 hours on the phone with TechConnect and they couldn't figure it out either. Any suggestions would be welcome.
