    Hi all,
    I am trying to configure networking in Linux VM with two Network Adapters (eth0 and eth1). I wanted eth0’s IP to be assigned statically for the local network and eth1 to be assigned by the DHCP for the internet connection.

    So, the machine should be able to ping another VM in the same local network via eth0 and should access the internet via eth1 without alternating either of the network adapter connection.

    Can anyone please guide me to configure the interfaces.conf (/etc/network/interface.conf) and NetworkManager config file or anything that needs to to make it work, please? Thank you.
    The below is my config and Local network is connected to VMNet 2 and another adapter is on NAT.

    # interfaces(5) file used by ifup(8) and ifdown(8)
    auto lo
    iface lo inet loopback

    # Primary network interface
    #iface eth0 inet dhcp
    allow eth0
    iface eth0 inet static

    allow-hotplug eth1
    iface eth1 inet dhcp



    Take that gateway off your static route, if its just to communicate solely with that 10.0.0 network. Use your gateway on the DHCP-issued adapter, and make sure when you type “route” that you see the eth1 adapter and gateway is set for your default GW.
