I’m not sure at what point, but some time over the past week or two, my 2Wire 3800 HGV-B router was upgraded to new firmware (by AT&T of course), version 6.1.9.24 or rather 6.1.9.23-enh.tm. I’m not positive this fixed it or if AT&T upgraded their firewall policy, but for whatever reason, my NAT loopback works now. This has been a major complaint by both tech-ey customers and AT&T tech’s on various forums I’ve read ever since U-Verse started it’s roll-out a couple of years ago. It’s a pain to work around if you’re doing any port-forwarding on the outside of the firewall and then attempt to access those open ports from the inside of the network outward. Well, if you get upgraded to the latest version or get the latest firewall rules from AT&T, you should be good now.

A much better firmware now exists for this router called Tomato. Check it: http://www.polarcloud.com/tomato

A friend of mine has a Linksys WRT54G v4, and there is some new hacked firmware out for it (hacked in a benevolent, legal way :). So we decided to upload this hacked firmware and give it a whirl. It worked with no problems and you can now boost the transmit power up to 251 mw (my WAP54G with hacked firmware goes up to 84 mw and I still get a connection from 6 houses down if that tells you anything). Theoretically, without any electronic interference between the router and your wireless card, you should be able to connect from quite a far distance (not sure exactly how far though as I have not tested it). This firmware will work for v1-v4 and seems to be really stable from what I can tell. So check it out and download it from here …
