The problem: I can access AWS by going to "localhost" or 127.0.0.1. People from the outside can access my AWS as well. However, I can't access my AWS from either PC on my local network, if I try accessing it using my WAN IP or domain name.

In other words, for ME and me alone, http://127.0.0.1:port/ works, but http://IP:port/ does not work.

My ISP blocks incoming port 80, so I am using port 8009. I have a router, and of course I am forwarding port 8009 to the PC running AWS. I have my software firewall correctly configured as well. The proof of this is that other people can access my AWS.

The URL is http://someurl.com:8009/ , and I expect that it will work for you, so long as I have it running at the time.

I am totally baffled and aggravated by this.

Oops, stupid me, I neglected to login before posting before.

Just to add... I have tried running the AWS-based PC in DMZ, and I've tried disabling the software firewall. I've looked in the router logs, and see absolutely nothing. I've checked the AWS "access.log", and it my connection isn't even getting through to it.

You must have an IP which is valid only inside your LAN and this is the IP you must use for local access. You can get that IP by executing on the command line ipconfig (on WinNT/2000/XP) or winipcfg (on Win95/98/Me).
Using one of these command gives you the IP assigned to your network card on your LAN.

Thanks, but I knew that. I know all about "WAN IP" vs. "LAN IP". The problem was I could only access my server using my LAN IP, while others could access it via the WAN IP. However, it seems to me I should be able to use either one!

Never mind, I give up on this. Thanks for the reply, though.

Just a small tip. On your computer, locate the hosts file:
* On Windows 95/98/Me c:\windows\hosts
* On Windows NT/2000/XP Pro c:\winnt\system32\drivers\etc\hosts
* On Windows XP Home c:\windows\system32\drivers\etc\hosts
If not available create it (with no extension), just hosts and not hosts.txt .
Edit it using Notepad and add the following line
127.0.0.1 my.dnsalias.net

or if you LAN IP is 192.68.0.1:
192.68.0.1 my.dnsalias.net

Save the file and close Notepad.

Than way, when you ask for my.dnsalias.net on your computer, it will point to the correct LAN IP without asking an external DNS server which will return your WAN IP.

Nice ??? :D

Thanks. I knew about Hosts, but hadn't thought about that workaround. It's a good tip, and I'll use it.

But I still should be able to access what "my.dnsalias.net" resolves to. And it drives me nuts not knowing why I can't! Oh well...

Thanks again, though; I really appreciate the input!

May be
Code:

tracert my.dnsalias.net

can give more information about the "wrong" way TCP/IP packets take ???
