NVG510 Bridge Mode???

Hi - after many VERY frustrating weeks, I was able to set up my NVG510 per the instructions on this site (http://www.ron-berman.com/2011/11/24/motorola-nvg510-help-page-for-att-u-verse-users/). Seems to be working (it has been a couple of weeks). But I have one issue - I don't know how to get to the NVG510 admin interface from behind my second router (i.e. the router that the NVG510 is passing through to). Is my only option to connect directly (physically) to the NVG510? Any suggestions? Thanks!

Make certain that the lan side of your router is not using the 192.168.1.xxx subnet.  If it is, change to 192.168.0 or .2, then point your browser to 192.168.1.254.  This is the NVG510's lan side IP.  Also, if you have purchased multiple public addresses form ATT, then the last one from the list they gave you should.  These are different from the broadband IP address.  Example, the system I just got through setting up the "public addresses the ATT gave me to use started with 99.30.xxx.xxx it included the wan side public address, the lan public address, and four additional public addresses.  ATT said I could set up the sub-net and dhcp to these and the vpn would work.   I had to set manual passthrough to the wan side MAC address of my router and use the broadband IP which was 108.xxx.xxx.xxx. 

The long-awaited firmware update is apparently now arriving. See this post:

Re: DNS on the NVG510

Summary: if you're suddenly getting error messages, try rebooting your router and NVG510. If everything works, check out the firmware version on the NVG510: 9.0.6h0d48 was the previous version. 9.0.6h2d21 is what's showing now. 6 months after it was due... wow! Hopefully we'll find it was worth the wait!

Oh, and still no bridge mode. I guess IP Passthrough is the new bridge mode where this gateway is concerned...

Okay, my testing shows this upgrade doesn't fix the DNS issues; however, some other posts suggest good news for PPTP users:

Well..  I've finally had enough (for awhile). After almost 10 months of IP passthru to a Cisco RVS4000 VPN router, I'm taking a breather. I had the RVS4000 in operation for about 5 months (before) on DSL in TRUE Bridge mode without a problem. Switching to U-Verse with the NVG510 in Passthru I can run for a month or two then one day I can't access certain websites (like yahoo.com) without reseting both the NVG510 and RVS4000. I'll run with the NVG510 for 2-3 months to see if my "outages" are strictly isolated to the NVG510 (and or AT&T service since AT&T's techs always point to my RVS4000 as the likely culprit).

What I'm giving up by using only the NVG510 is the ability to "loopback" to access my FTP server and security/home automation system, which currently uses a single interface from an iPhone/Anrdroid and VPN aceess to my home network (provided by my VPN router). I hope to add VPN duties to my FTP server (if I'm stuck in this configuration). The other major feature I'm losing is the ability to monitor attacks and probes to my intranet routed to a syslog server. This has helped me to be more proactive in securing my machines from outside attacks.

I'll continue to monitor this thread to see how eveybodies doing and to see if a true Bridge Mode becomes a reality.   

I've had to reboot my router and NVG510 every few months. Whenever you have to do it, check the logs on the NVG510. It looks like AT&T is remotely updating the NVG510 from time to time. After a remote update, everything needs to be restarted, but there's nothing that tells you that - it just starts working erratically.

Hello,

I am about to have u-verse Internet and Voice installed (upgrading from separate DSL and analog phone service from ATT).  I have a large AEBS home network, and plan to utilize bridge / ip passthrough mode on the NVG510 modem / router.  My question is, will setting up the NVG510 in bridge / passthrough mode in any way affect u-verse voice and / or u-verse TV service [assuming I add  TV services at a later date]?

Thx,
Peter
