PACE 11.1.0.531418 DMZ Issue

I put my router behind the PACE gateway and set the router as DMZ.  The latest firmware is crapping out my fiber connection where I'm only able to get 50mbps down and 1-200 up.   I thought it was my router crapping out, but apparently when I connect any other device directly to the gateway, I'm able to pull 940mbps up and down.  I swapped an older router and placed that device in the DMZ And it starts acting up and the previous router started working normally.

 

Can someone look into this?

Re: PACE 11.1.0.531418 DMZ Issue

My 5268 recently received the 11.2.1.531810 update, but it broke my DMZ+ setup (ASUS RT-88U) that had previously been working. Internet connectivity stopped working for all clients connected through the ASUS router, but they could access the internet directly from the 5268. An inspection of the 5268 firewall log revealed that it was seeing the traffic from my router's IP address as a "TCP flood" attack from *inside* the network and (I assume) administratively blocking all traffic from that IP after a few seconds which effectively disabled Internet access. Had to downgrade to 10.7 to get it working again.

 

Has anyone else experienced this issue?

I haven't been upgraded yet. I had been thinking of manually upgrading but
this gives me pause. thanks for sharing this, hopefully it's a one-off but
knowing how AT&T operates I don't have much hope.

I upgraded and speeds are back to normal in dmz+ mode but then all my wifi calls drop.

 

Not sure what to do at this point.

Yes all ipsec tunnels seem to be non reliable. Wifi calling works a bit better on airplane mode but still broken. Sms on wifi don't work outgoing maybe 5%.

Thanks for confirming. I've gone back to allowing individual applications through the firewall.

I just got off with AT&T regarding the exact same issue (if I port-forward/DMZ, speeds drop to 50Mbps on 11.1.0.531418).  I tried to get an update to the new firmware and tech support couldn't do it so they tried sending me a new Pace modem.

 

Hours later, I noticed they're trying to charge me an extra $7+/mo for equipment fees.

 

I chatted with them, explained the situation, and complained.  They're now sending me the Arris and they've changed me back to my old fees.

 

I'll update later if I can manage to get this to work with the Arris.

suggest getting a proper home Wi-Fi system and putting the at t gateway into bypass mode.  If you want reliable Wi-Fi calling.

I was about to say the same thing.  They will likely send another Pace unit.  Are we at the year mark yet with this issue??

I think October makes a year.

 

In the meantime, I'm still going to stick with 10.7, as it's working as desired for me. I've got DMZ+ pointed at my router, and it does the rest. For the ways I use it, no problem whatsoever. Speeds stay ~940 up and down for me and I have no issues setting up remotes, FTPs, or whatever else I need.

@Swerved @Are you doing any WiFi calling with your 10.7 fw over your router WiFi?  Working well?

THU update on AT&T's fix.  I ended up getting a Pace modem with the same old firmware on Tuesday.

 

By Thursday morning, the old modem no longer worked so I had to switch to the new one.

Of course, after set-up it had the same speed issue with the DMZ.

 

Now, I'm fighting with AT&T Tech on the phone again to get a BGW replacement.

ok.  I've been sent my 3rd useless Pace modem.

 

They are scheduling a technician to bring in a BGW210 on Sunday.  I'll update after setup.
