View Full Version : [ubuntu] Networking or security problem ?
February 25th, 2011, 10:51 AM
Please see this post (http://ubuntuforums.org/showthread.php?t=1693652) , as I'm not 100% convinced that this is a security (firewall) problem.
Could be network, I don't know. :confused:

I can't ping 'out' to the internet, either by IP or by domain name on the client computer, yet can do 'all' on the gateway.

The only way I could get the client to have access to the internet, was to reboot the gateway computer into Windows XP, .. works fine.
Any way I can check/double check that all the network settings are correct ?

The setup is as follows ..
Internet <<==>> ppp0 <> Ubuntu gateway <> eth0 <<==>> Client PC
The gateway computer has the 'share' option enabled, and the client computer has the gateway IP address set in NM. I use NM for both computers.
Gateway computer 192.168.1.100
Client computer 192.168.1.101
Problem - can connect to the internet okay with gateway, but NOT client.
Here is the ifconfig from gateway
removed per request.
Here is the ifconfig from client
removed per request
I have GUFW installed on both computers, but there is nothing in the logs to suggest a 'block'.
If I restart the network on the gateway, I have to do this again ..
sudo ifconfig eth0 192.168.1.100
I can also reboot the gateway into Win XP, and that connects okay, AND the client can then connect.
So is it the Ubuntu gateway or the Ubuntu client that needs some tweaking ?

Can UFW/GUFW do ICS ??

I still can't access the internet from the client computer. :(

Closing this, as it is a duplicate. If you want a post moved, please use the "report abuse" link and ask for it to be moved.
I will move your other thread to the networking form, as what you want to do is a networking issue.
