VPN over Uverse

[altrenda]

I inherited a client and I am having trouble getting VPN to work.

Setup
ATT Uverse NVG510 modem/router (only provider available in this building)
Barracuda X200 Firewall handling DHCP
3com unmanaged switch
8X8 hosted voip phones > Computers connected to phones
Windows Server 2003 with AD, used as file server
Using DynDNS Dynamic IP, as recommended by Barracuda.


The problem is the NVG510, it does not allow true bridging, so it assigns an internal IP to the firewall.
UVerse RG > NVG510>--192.168.1.1 static to Firewall> 192.168.2.xxx to network.
I've tried many workarounds I've found online, but can't VPN to the Barracuda using their client to site VPN.

Question
Anyone have experience with the Uverse NVG510 and VPN?
Other modems available from Uverse that allow Bridge mode?
Other things I might try with this setup?

I ran into this problem a long while ago, too. There was a thread on here about it....

Yes you can put your firewalls behind the U-Verse gateway, and have them pull a public IP address...and do VPNs 'n all that. We have quite a few out there in production.

Under Home Network tab, Subnets and DHCP, Public Subnet....you setup your public IP range (you should get a range of 5 usable public IPs). Set the WAN interface of your edge device to "obtain auto" and it will pull the first IP in the DHCP handout range.

The cascaded router option..I don't touch that, doesn't seem to be functional yet (might be in updated firmware?)

One of my colleagues just said he even got a manually set static on his router to punch through in the IP passthrough mode. Firewall tab, IP Passthrough link. Flip on default server, ...and type in the current address that your router has on its WAN port. It's sorta like the DMZ Plus mode in the prior 2Wire units.

Update: this program is great. for $3, put it on my Nexus 7 and within 5 minutes I had true Bridge mode on Port 1 of the NVG510.

Interesting to read the reviews from Att installers that use it.

Thanks

May give that app a shot...instead of loggin in with my laptop...although the steps I do to reconfigure it to pass the public IP are quick and easy...I have always have to spend a minute flushing out my browser to get rid of that redirect.ha error that this Android app can avoid. Reps sent!
