I'm a new Ubuntu user and I did this steps recently, with 'AskUbuntu' support: - installation of Ubuntu, ownCloud server + client, Oracle VirtualMachine - configured ddns (duckdns.org) - port forward, necessary for the ddns work properly.
I can access Owncloud from other machines, using my local network. But I can't access my owncloud server when I'm outside of my local network. I'm using wired network at home, where the Ubuntu machine is installed.
Talking to a friend I realized that I need to set up a static IP to make the DDNS work properly and, then, have access to ownCloud from outside my local network. I searched the documentation at https://help.ubuntu.com/lts/serverguide/network-configuration.html
Then, I followed all the advices and changed the files /etc/network/interfaces /etc/resolv.conf /etc/hosts
I used my address, netmask and gateway. I'm sure the numbers used to address, netmask and gateway are correct. I used 'ifconfig' and route -n to check it.
I also restarted the network, shutting down the system. After start the machine again, the wired network doesn't work.
Please help me to find where is my mistake.
Thanks a lot!
