port 80 blocked by my ISP

Hello everyone,

I use red hat linux 7.1 and I have a ISP which block port 80 and my server is connected through Cable modem.I have a second server a way from the firstone with a fix IP wich works as DNS server for the one behind CABLE MODEM.
I was wondering if in my second server I can do something to send DNS queries to other port which may be open?

Cheers

aehh, you seem a little confused.
port 80 is www, not dns.

you can use RINETd to re-route internet connections. for example:

user -> server outside provider:80 -> server on your cable connection:8080

they should not block ports above 1024 because then you cannot surf anymore nor use most other services ... and this masquerades your www server as a proxy . change port numbers (8080 to anything) if it still does not work.

Thank you for your help,
Indeed I was a bit confused between dns and apache ports.
My last question is now for acceding my site do I have to type always:
URL or there is a way to put it as default in apache to listen to this port.

you can make apache listen on port 8080, but this won´t help since browsers by default access it using port 80.

this is what "rinetd" is for... put it on a machine that has port 80 open and it forwards them to your machine on 8080. they can´t even notice

Unfortunately that won't work because he won't get any inbound connection on port 80, thus unable to forward nothing to port 8080.

if he does not get inbound connections to port 80, why should he not get any to 8080 like for active ftp?

ah, looking at his posts again...
question to mashadiyahya: is your DNS server on this cable connection too or is it outside? i assumed it is outside...

Hi ,
I could install rinetd and use it but still the only problem is My IP
is a Dynamic IP and I use an external service for a Dynamic service, so if I use IP redirection in Rinetd,and when my IP changes I have to reconfigure the config file manually. Could I use virtual host name instead of IP address in the config file ?(like : mydomain.com www 192.168.10.1 www)?

Thanks for any help.

look at dynamic dns. (search on google, i don t have and url for you right now... i think it was dyndns.org or dyndns.net or .com or what)

then you can call a script everytime you connect to the ´net and tell them to update their dns entries...

for linux there is a dynamic dns client. never tested this one though...
