I can't get Flashbuilder 4.6 to connect to remote Linux server on port 80

Question

I'm using Flashbuilder 4.6 on a Mac (Snow Leopard). I have a new CentOS 6.2 Linux server with Apache webserver 2.2.21 on it, then installed GlassFish 3.1.1 application server on it, then installed mod_jk to connect Apache and Glassfish. Everything is installed on the same server. I verified that I can deploy an example war file (web application) in Glassfish and access it fine using either,
    mydomain.com:8080/mywebapp  (uses port 8080, which is direct connection to GlassFish)
    mydomain.com/mywebapp   (uses port 80, which enters Apache and passes through mod_jk to get to Glassfish)
This works well (no errors in any logs files).
Then I download BlazeDS from Adobe website, create a hello world application with it and deploy it in GlassFish. I next try to setup a new Flex Project in Flashbuilder 4.5. Using the wizard, I come to the section (under Server location) where I need to input a Root Folder and Root URL. Everything works fine when using a Root URL of http://mydomain.com:8080/mywebapp, meaning, I can click on the Validate Configuration button and Flashbuilder connects to the server.
But if I enter in the Root URL input field http://mydomain.com/mywebapp, then Flashbuilder cannot connect to the server. I need to eventually close port 8080, so I need this solution, which uses port 80, to work.
I made sure that the httpd.conf file VirtualHost section does include a `JkMount /mywebapp worker1` statement, and I can even look at the mod_jk.log file and see that Apache correctly opens a socket for mod_jk to communicate via AJP between Apache and GlassFish (with no errors or warnings) when the address `mydomain.com/mywebapp` appears on port 80. The GlassFish server.log file also shows no problems.
I'm stumped what to do next. Does anyone have experience connecting GlassFish, mod_jk, Apache, and Blazeds (or LCDS, should be similar)? If so, do you see any differences in my setup compared to yours? I'm only trying to use RemoteObject (not messaging, or streaming, etc.) with Java POJOs.

Hi!
Thanks for the reply. No, my ISP isn't providing me with three IP addresses, just one static address. And the VDSL modem...not a router, but beyond that, don't know much about it. Do have a switching hub, however, a gigabit thing that so far is working great.
Managed, somehow, to get everything working, however. Really don't know what I did. But I can now take the MBP off the wire and connect to the other Macs without turning on Airpot on those machines. Next step now is to take the MBP to another location and try to establish a connection to the home network via Desktop Transporter or Vine. That's the Holy Grail that will allow me to sever the cords that keep me from straying too far from home during working hours. Love to sit at that coffee shop across the park and do my work from there!
