Cannot access Apache webserver from internal network, but I can from outside...
 

Hi there,

Im very new to Linux so please bear with me...

I installed XAMPP for Linux and have apache running, everything was working great up until a little while ago. I can no longer access the webserver via its internal IP (something i was able to do just a few minutes ago). I can still access it via my external ip address.

Anyone know whats up?

Thanks in advance..

Do you have 2 ip addresses on the one NIC or 2 NICs with different IPs?

Can you post the output from:
ifcontig
route -n

What is the internal IP of your client?

neither, this is just in my home envrionment, so i just have it plugged into a switch and it obtains an internal address from our home router. I have setup a port redirection so that it will always forward traffic from port 800 (my isp blocks 80 so i had to change it) to my linux machines internal ip address. Yet for some reason when i point to its address (192.168.0.100) it does not reply, but when i point to my IP in internet explorer it does.

Here is the output of those commands:

Ifconfig:

So internally are you pointing to port 80 or 800?

800

So is apache listening on port 800 as well as 80?
netstat -nlp

it should just be 800

here is the output from netstat -nlp, for some reason httpd is listed twice

tcp 0 0 :::800 :::* LISTEN 1042/httpd

tcp 0 0 :::443 :::* LISTEN 1042/httpd

You are running apache on the 800 port that you configured and the 443 is for SSL.

To be able to see the apache from your explorer without having to add the :800 after it, just edit the httpd.conf and add Being xxx.xxx.xxx.xxx the internal ip.

i cannot even access it with :800 at the end of the internal IP
