  • Network Connection Destination Host Unreachable

    Posted on

    I have set up a Red Hat Enterprise Linux Server Release 6.5. I currently cannot connect to this machine from the local network nor can I connect to the internet or the internal network from the server. This has been a problem since the day it was set up and I have been unable to resolve it. My file settings are below.

    Firewall is disabled

    If I set the network card to DHCP it will take me to an internet connection for the internet provider requiring a login. If there is anything else you need let me know.
