Can't connect to portal.


Hi,

I'm using CentOS 6.3
Apache Web Server


I can't connect to a ticket system portal from another computer outside the network.

The ticket system is running on a virtual machine with NAT.

Any more info I should provide? Or any step should I take?

EDIT: I changed to Bridged and still can't.
EDIT: I can not access the portal on the same network from another virtual machine on the same network 192.168.1

Hi,

Did you verify that Apache is running? Can you run the following command on the box with Apache installed and post the output:
Code:
netstat -tnlp
Kind regards,

Eric

Yes, Apache is running, and I can access the portal locally, but not from another PC on the same network.

Hi,

How about posting the output of the command, run on the Apache server, I posted? That will show us on what IP Apache is listening and might be a first indication.

Kind regards,

Eric

Well, you have nat? The host box is running linux, right? Can you show us the output of this?

iptables -t nat -L -nv
iptables -L -nv
ip addr show
ip route show

Have you tried using a sniffer on both network interfaces (interface to network where traffic from box is coming, interface to VM)?

Okay, the output of netstat -tnlp

I tried lining up the output, but would not.
I hope this helps.

EDIT: I can ping the server with the ticket system portal with all clients, and the server can ping all clients.

Is that output from the host or from the guest? And what about iptables?

From the guest, yes.

Yes, I have nat but not using it, I'm now bridged.

The host box is running linux. The guest box is running linux.

What option do you want me to use with iptables?

That is all the output from the guest(VM)

Thanks a lot eantoranz.
