I use Apache on Red Hat Linux 7.2 to host my website. since My ISP, Adelphia, does not offer static IP, I signed up at www.no-ip.com
to use their free DNS service.
The only thing that I changed was the server name on httpd.conf (I put dagadaga.no-ip.com as the server name) Then I did a ./etc/init.d/httpd restart to restart the daemon.
I can find my website, so far so good.
when I go to my friend's house, however, I caanot find my website anymore.
I then did a tracert on my friend's windows system and I was able to trace all the way back to my IP (I tested using both the IP address and website address and both worked).
I also did a ping and was able to receive response from my computer.
Interestingly, I can do a telnet to my host from my friend's house without any problems.
Given these observations, can anyone tell me if my ISP blocked my Port 80? Or is there a step that I'm missing? Any alternatives to go around if my ISP really blocked Port 80?
Thank you in advance and I appreciate every feedback!
