I am trying to expose a simple server over internet listening on port 80. I've configured iptables to accept incoming connections over http, so I don't if this means something but when I use traceroute to my own IP address I get:
190-90-90-90.dyn.dsl.cantv.net (184.108.40.206) ...
(Obviusly that's not my truly ip address but is an example). If I access to this address (including dyn.dsl.cantv.net) I get a right response using the browser in the computer but if a try to access from external using a mobile web browser I ever get
too long time to response
This means that my ISP is blocking incoming connection from port 80 (http)?
I don't understand what is happening because I created another simple server but listening on 8443 using a self signed certificate (ssl) and going to https://220.127.116.11:8443 from external, using my mobile web browser I get a right response.
I don't know a good place to ask this question, but I think is maybe related with networking, I hope you can help me.
