run web server behine router quickcur 07-16-06

I run Apache on my home PC which is behind a Netgear router. It gets
dynamic IP address from Comcast. I would like to visit the web server
from outside. I went to dyndns.org and registered an account
"mydomin.dyndns.org". I also did port-forwarding (port 80 for http) on
my router. But I can not "ping" or visit my web server from outside
with browser.

I do not think my isp is blocking port 80 because if I do not use the
router, I can visit the web server from outside.

What did I do wrong?

Thanks

Hello,

You most likely did not properly configure the router, since that is what
is failing (it works without the router). This means that it cannot be a
DNS issue, and it certainly cannot be an IIS issue (is IIS even involved
in this?).

If you are sure you have properly configured the router, do you really use
a machine outside the router? If not, perhaps your router does not support
loop-back?

Which Netgear router? Is your firmware up to date? The router firmware or
configuration seems to be
the problem.

I have a similar setup with my Linksys WRT54G router connected to Time Warner
Roadrunner service. On
one of my internal machines I run a subversion server for the sources in a
couple of program
projects that I host. I also have a registered a domain name with DynDNS.com.
The only thing I had
to worry about is that I have 3 other computers behind the NAT router and I use
DHCP for them. To
ensure a constant IP address for the SVN server, I assigned a fixed IP address
outside the dynamic
range. This way the server always has the same internal address for router
forwarding of the SVN
packets.

Ping is a different port and probably blocked by your isp as well as
your router.

If You can reach the web page from outside with out the router you have
'nt got the forwarding right in the router. FYI your router may be
blocking the returned info from your website to the outide world.

Thanks for your emails.

Here is my router config from http://192.168.1.1/start.htm

# Service Name, Start Port, End Port, Server IP Address
1 AIM 5190 5190 192.168.1.2
2 HTTP 80 80 192.168.1.2

I do not know what else I should do.
