3800HGV or 3800HGV-B Networking Issues For Home or Business Use


3800HGV or 3800HGV-B Networking Issues For Home or Business Use

I wanted to let everyone know that the issues on networking this router can
be resolved easily. I spent 2 weeks trying to get my 2Wire 3800HGV-B AT&T Uverse
router working with all my devices in my office. I finally found a solution and
its not bypassing the router by piggy backing another router and putting that
router on DMOZ, this does not work as it only allows the piggy backed router to
pass through the firewall, it will still block other devices it sees coming
through the piggy backed router. In most cases for business who use IP Phones or
ip network printing, this is a must, even with some home users who use network
printing etc...

1. You have to get rid of the old, adding a static ip to your device technique,
this is not longer an option on this router cause it actually assigns the ip you
tell it to, to that item via mac address, so it will only give the devices that
are set up as dynamic, the ip address you tell it to in the router itself.

2. You can only DMOZ 1 device, therefore it will block all devices, servers, ip
phones, printers etc...

The solution was simple, I paid an extra $15 per month for an additional 10 ip
address's cause I had an idea that if I assigned each device an ip, that it will
have direct internet access... and guess what? After, I went in to the router,
remember, I keep the devices themselves on DHCP, and take it off static cause
the router will do its job on assignment.. So I went in to the router and
assigned each device its own ip.. You log in using admin password... You select
"home network" at the top of the page, then advanced settings under home network
in the sub menu, You will then see a "Current Settings Box" on the right side of
the page, scroll down till you see and click on the "Edit Address Allocation"
button. Here you can see all your devices, if the name does not show up, you can
know its that device by ip address you see, or the mac address. For each device
you are assigning an ip to, you will need to do 5 things.

1. Under "Address Assignment" you need to select "Public (select WAN IP

2. Under "WAN IP MApping" you need to select the ip address you want to assign
to that device, you would be better choosing your own by selecting "Public
Fixed: with the 0's being the ip of your choice"

3. Here is the important part... You need to uncheck the "Firewall" box to turn
off the firewall, but first before unchecking the box, you must save your
current changes so that the dedicated ip can be assigned because it will not
allow you to uncheck the "Firewall" box till its set up as a dedicated ip
device. Once you save your settings, uncheck the firewall box and save again...
Do this on all the devices you want to pass through the firewall like VOIP
Phones etc.. If the firewall is on, it will block transferring from IP Phones.

4. Make sure anything you assign an ip, that if it has an admin which you can
login to using the ip, that you set up a password on each device that can be web
accessed, hackers will try and mess up your settings for fun if you do not
password them out.

Thank You,
