help with Frontiernet, dyndns.org and Apache

[caseyg]

Good morning to all,

I have a domain set up through dyndns.org with a residential isp (Frontier DSL w/ DHCP). I'm running Ubuntu Studio with Apache2. I can reach my webpage from within my network at home and any other computer on Frontier DSL. Tyring the URL from PC's on other ISP's does not work (web page can not be displayed). Yet if you ping it from that PC it will show the proper IP according to dyndns.org but no reply from my Frontier modem. All firewalls have been disabled on the modem. I've verified the dyndns is working correctly. Any thoughts!!!

Your ISP is probably blocking port 80. You need to run apache on an
alternate port and use dyndns webhop service to cause incoming web
requests to be forwarded to the alternate port. Webhop is another
of their free services.
