Problems Installing Sonicwall TZ-215 with Uverse Internet

I've recently purchased a SonicWall TZ-215 VPN/Firewall.  I attempted initial setup today and am having some challenges.

 

I've gone into my DG and set the SonicWall up in DMZplus

 

The DG is correctly pushing its public IP address down to the SonicWall WAN port

 

I can ping the SonicWall IP address, and I can ping external IP's (8.8.8.8)

 

I cannot get internet access though, and I cannot ping the DG's DNS (.254) IP

 

Any thoughts on what I've got wrong?

Re: Problems Installing Sonicwall TZ-215 with Uverse Internet

The internal LAN subnet of the RG (Residential Gateway) must be different than the internal LAN subnet of your SonicWall.

The default subnet of the RG is 192.168.1.0/24, with the RG at 192.168.1.254. So you need to set your SonicWall's internal LAN IP scheme to something else, for example: 192.168.2.0/24, with the SonicWall at 192.168.2.1 or 192.168.2.254.

That fixed it.  Thanks so much!  I had both SonicWall and ATT tech support help and neither caught that small piece of the pie.  Much appreciated!

Re: Problems Installing Sonicwall TZ-215 with Uverse Internet

I have a TZ105 and setting the NVG589 up in "pass-though" is quite simple. What is a problem, is setting up a PPTP VPN in the SW and getting a connection to the VPN Server. How can this be achieved?

 

Thank You,

Hi @ohiopcman,

 

Once you get the U-verse gateway setup in passthrough mode, make sure you can browse the internet. After that, I found a set of instructions on setting up a PPTP VPN on the sonicwall here.

 

Hope this helps.
