dns is not working through internet
Hi, i recently installed echp and tested over mi lan network without any problem, so i try to put into the internet.
i'm from argentina, so i went to nic.ar, the page who manage the domain names , dns etc.
i register a dns for my ip address (1 dns per ip is allowed).
i register a test page and delegate the dns to the one i had register in first place and other at random.
i had all the necessary ports opened, like 53,80,21,443 etc.
i don't know how much time take to the dns of my server to translate the domains or how can i make them work.... right now, i had my domain in nic.ar with primary dns ns2.lancube.com.ar wich is pointing to my external ip address, but
i can't reach any web page or doing ping to the dns.
i only can acces to some webpages in my ehcp server in wichs i am using as secondary dns one that works from a free dns server.
it has been no more than 20 hours since echp is online.
thanks in advance

126.96.36.199 if this is your
if this is your external ip, I tested, does not accept dns requests... Your port 53 seems closed.
This caused mainly by one of these:

hi i have checked all the things you said...
i had a firewall router in ip 192.168.0.254 ...
my firewall config in : http://www.lancube.com.ar/imagenes/dns-firewall.PNG
my port forward config: http://www.lancube.com.ar/imagenes/dns-portForward.PNG
bind in my server over putty: http://www.lancube.com.ar/imagenes/dns-bind.PNG
i think those config are just fine, the only thing is ...
"your server/server's internal firewall.. check those "
my firewall/router is running on 192.168.0.254 ... what do you mean with your server/server's internal firewall??
thanks a lot

You have a problem at:

According to that: you allow dns from internet to your server, but you do not allow from your server to outside world.
This explains everything. Thats why you/your server can reach internet, but internet cannot reach you.
Solution: the source column should be Any for both tcp,udp, port 53.
your port forward config is ok.
"your server/server's internal firewall.. check those ": I mean, sometime, people install firewall on servers too... if you did not install, dont wory... but if you/somebody installed firewall on your server, you should enable ports on your server too.. to check, on another computer on your internal network, on command line:
you should see something open..
