Thank you sir for your prompt response.
Then I think I have a problem. I had HFS 2.0 working for 3 days and everything was working fine and my friends and family were able to access my computer. But suddenly there was a 30-second a power outage last night that screwed up everything. I had to reboot my router. After this reboot I lost everything.
I did exactly the same configuration I did the first time setting up my router and firewall and evrything but every time I do the Self Test, it doesn't go thru. I disabled both firewalls but the same result and the same message that I am behind a firewall or a router. Your help will be highly appreciated.
my router is Linksys WRT54G
