Something is Fishy About My Network

Hi,

I'm running Fedora 10 x86_64 and I really think something is odd about my ability to network and I think it's all pointing to DNS.  First, I've been running Linux (full time) for almost a year, but I am still a newb.  There are still some Windows concepts that I haven't been able to shake yet, so please be very simple yet thorough with your replies (I'd appreciate it).

So here's the meat of my cry-for-help caserole. 

• I'm having a problem pinging my hostname.  I'll ping it and 127.0.0.1 is the resulting IP.
  
• I see that my router has given my computer an IP address, but it doesn't have the hostname in its table.
• I can't ping, by host name, my computer from any other computer on the home network.

So because of those issues, I can't properly network my linux box with other computers in my home network.  I just found out (from a friend) that I had an internal firewall turned on.  I didn't even realize that Fedora shipped with a firewall.  From my Windows-days, I've learned that software firewall causes too many headaches.  So; I disabled the firewall I discovered in Fedora.  Thanks for any feedback.

system-config-network 1.5.95
I'm not all that handy with command-line network configuring yet so I'm using the GUI program system-config-network.  In my DNS tab here are my settings:

• hostname: unicron.cybertron
• primary dns: 192.168.1.1 (router)
• secondary dns:
• tertiary dns:
• dns search path: unicron
