My isp blocks port 80 , so is there a way to foward the port 80 to a diff port ? so i dont have to add the port on the browser.....

yeah you can run a iptables firewall and write a rule to forward the port

man iptables for more info

Type the command man iptables in a terminal/console, and press return

Correct me if I'm wrong, but if his isp blocks port 80, that would mean that the port was either blocked from the source directly, or from the router/modem that the isp provided you with.

So, if you wanted to redirect a certain domain.com to go to a different location, maybe you could look into dns as a solution. I don't know that much about dns, but I think that could be a solution.

Anyone else?

yeah you are right. if one runs ip forward on the local machine the packets must first reach the machine on the initial port from which they will be forwarded. if the ISP is blocking the packets then they wont reach the machine and hence they wont be forwarded.

i am sorry i missed that one before

what you need is a port forwarding serive provider. there are lots of then and some are free the last time i checked. do a google search and you can find some.

I have also been looking at the port forwarding services. Like http://no-ip.com/ but this does raise an interesting question though. Could you make a dns server that takes a domain name without the :8080 for example and translate it go be forwarded to a certain IP with :8080 attached?

Just wondering?

Are you sure its your ISP that blocks port 80 or your router? Are you trying to host a webpage? For my webserver to be visible to the outside I have to forward requests to port 80 on my router to my webserver.

Yes my new isp blocks port 80, which im so mad ..... and i hate to add the port to the browser.....

Yes this is my RH8 server ...HELPPPP

Anyone has to had the same problem. My isp block port 80 so how can i get around this >? without adding the port to the browser? please help

i know i can do a web redirect , but that sucks because it will still show the port on the browser status bar .....

HELPPPPPPPPPPPPPPPPPP PLEASEEEEEEEEE

if the isp blocks traffic to port 80, then there really isn't anyway to serve the content without using another port, which will require you to specify the port number in the URL. one options is to tunnel connections from someone else's box, but I can't imagine anyone offering to do that for you (it would be easier to simply host the content there).
regarding the question in post 7, the DNS doesn't handle port numbering, only the addressing, so it would not be possible to have lookups automatically append :8080 through DNS

I just did a workaround to this - it's super easy

I went to no-ip.com and setup a free account.

for the first account you make a redirect called like foo2.no-ip.com
and you direct that http address to your home IP

THEN you create a WEB redirect that links foo.no-ip.com to foo2.no-ip.com:8080 (where 8080 is the port you've chosen for your http server on your local machine)

then foo.no-ip.com is your address, and your ISP can KISS OFF!!!

SCREW YOU COX COMMUNICATIONS!!!!!

www.dynu.com offers port forwarding. Check them out. I have never used their port forwarding service, but I think they alter the name for you (i.e. changin port 80 to port 8080) without the user having to type in the port number.
