Hi,

I have setup a Ubuntu server with Ubuntu Enterprise Cloud. The server is connected to a private LAN with DHCP and Internet access (via a gateway).

At first, the server was working fine. It can ping the internet. It can also ping other machine inside LAN.

The problem happened after i let the machine idle for more than 1 hour. When I want to use the machine again, I can't ping the internet anymore. I can only ping the machine inside LAN.

I try to ping the server from another machine and it's working. Then, i ssh into that server from another machine, and I found that I can ping the internet from that server.

It seems that there are some problems in the routing table of this server. Can anyone help me on this?

Thank you.

Max
