DMZ+ mode on Pace 5268AC to my asus ac3100

As I understand it, the DMZ + setting should be forwarding all traffic to my Asus router after enabling DMZ+ to it and changing the advanced firewall settings. However, I am unable to get ports to forward through to my Internal devices. I had this configured on the Pace itself until adding the Asus into my network.

So does DMZ+ actually forward all ports to my router or is it just "kind of a DMZ, but not really"?

Check out our information page on DMZ+ configurations for detailed setup steps. 

2Wire/Pace Gateways
The passthrough mode for 2Wire/gateways in referred to as DMZplus mode. The device that you would like to be placed in DMZplus must be connected directly to the gateway and configured to obtain an IP address through DHCP.

  1. Open a browser on a computer that is directly connected to the RG.
  2. In the address bar, enter http://192.168.1.254.
  3. In the GUI select Settings, then Firewall, and then Applications, Pinholes, and DMZ.
  4. Under Select a Computer, click the device name or IP address of the device you wish to put in DMZplus mode.
  5. Select the Allow all Applications(DMZplus mode) radio button.
  6. Select Save.

Well, I got this resolved. The ports are forwarding, the network connection of the machine I was trying to get to was set to public and the firewall was blocking the ports. after changing the network connection profile to public all is well. Should have checked this yesterday buit I didn't even think about it.

As far as I know, DMZ puts your router right on the AT&T network. You need to check to things to confirm you are in DMZ:

  1. On the 5268ac Settings/Firewall/Status panel do you see that Asus is listed as being in the DMZ?
  2. On the Asus, is the upstream IP address something other than a 192.168.1.x?

Yes, it is listed as having all ports forwarded to it. And shows as a DMZ device.

The Asus has the Public IP. I have ports forwarded as I always have when I was on another ISP. But the ports are not showing as opened.

I have seen this issue before and I believe it may be an issue with the 5268ac. Passing to AT&T for comments.

There are some reported issues with other ASUS routers' reliability in DMZ mode, have you been able to test your setup yet? Any input regarding reliability and performance is appreciated since I am shopping for a router that works with 5268AC.

I know of no issue specifically related to ASUS routers behind U-verse Gateways.

This question may not be related, when using a third party router like the Asus AC3100 or any other third party router, is there any other setting needed to be changed with AT&T's residential gateway under the Firewall section of the "Advanced Configuration" tab? and which box to check and uncheck under the "Advanced Configuration" tab for DMZ+ to work properly?

 

need help with the correct settings in the "Advanced Configuration" Tab to have DMZ+ mode running correctly.

 

Thanks

Realize that some devices behave poorly when assigned to the DMZ, my Airport Extreme is one.

 

  1. Either factory reset or configure your Asus to accept a DHCP address from the 5268ac.
  2. Once the Asus is up and running, find out what IP address it was assigned.
  3. Go into the 5268ac and the Settings/Firewall/Applications, Pinholes and DMZ page.
  4. Step 1) Select a Computer. Select the Asus. If you don't see the Asus, key in the IP address it was assigned and select Choose.
  5. Step 2) Select 'Allow all applications (DMZplus mode)' and then 'Save'
  6. Go to Setup/Firewall/Status and confirm that the Asus is now in the DMZ

I'm doing this as well with a custom build Sophos UTM on a Zotac CI323 Nano. I have gotten the UTM in DMZ mode, but have a question about the other 3 ports on the Pace.

 

Once I have my UTM in the DMZ working, are the other 3 ports on the Pace useless? And does it create a conflict if I put another device in there? I'm thinking the UTM has the WAN IP, and if I put something into one of those ports, it might...  Or is it another WAN IP, and the other 3 ports should work fine to test with?

 

The only reason I have done this is to test my speeds, which have been fluctuating for the last few days.

Thanks.
