Hello all
I'm not sure how to search for this. Over an hour on Google has told me I'm obviously using the wrong search terms, but I'm at a loss.
I have a domain. Let's call it "myself.com". On this domain I have several subdomains, which for now all point back to the same machine as far as public DNS goes. I have subdomains for
www., mail., and gallery., to name a few. Again, for now, they all point back to the same box on my network.
Since I have a dynamic public IP address, I registered with a dynamic DNS service to both register my domain names as well as handle DNS updates for my changing IP address (which for as often as it changes might as well be considered static).
With Comcast, I had it set up with NAT and specifically forwarded ports 80, 443, ... well, all the typical services ... to the same DHCP-reserved private-IP address on my box. DHCP was served from the wireless access point/router we had. It was easy to set up, especially after putting DD-WRT on it.
We recently converted to AT&T U-Verse (which sucks royal a**, by the way). I've gotten a DHCP reservation set up, and from the public Internet I can still get to all my subdomains, and I can still view my webpage.
HOWEVER, before, on Comcast, I could type in "www.myself.com" in any web browser and get my website, regardless of whether I was on my own home wireless network or anywhere else. Now, on AT&T, I can only view it if I'm on a network other than my own. If I'm on my own home wireless, I have to specifically go to the private IP address to view the site, e.g. I have to type 192.168.100.60 as opposed to
www.myself.com.
Does anyone know either (a) what I should search for to find the answer or (b) the answer itself?
We have a 3800HGV-B Gateway as provided by AT&T. I don't know off the top of my head who makes it (and I'm not near it ATM).
In other words, I used to be able to connect to my web and mail servers from any other network or from my own network, by typing in
www.myself.com on any web browser, regardless of which network I was on, and view my own web server I have set up. Now, I can only do that from outside networks, not from my own. I want to be able to view it on my own network too. I'm certain 100% that it's a setting in my gateway, but I'm not sure what setting that would be (if the gateway is even capable of doing that).
It's as though the AT&T device won't route a port-80 request from a device on its internal LAN to the proper privateIP:Port on the same network.
I have checked the DNS entries, and they're correct (and obviously must be if e.g. I can view the site from work or a neighbor's house or my G1 cellphone using the T-Mobile Edge network).
Thanks in advance!
