If you had to make these changes you might also like to modify ''/usr/pluto/bin/Diskless_ExportsNFS.sh'' accordingly as well since that seems to be the template from which ''/etc/exports'' is generated.

Usage Information

When switching from a Single NIC setup to using dual NICs, Changes need to be made in several places. Order of these operations is important.

  • Web Admin: Show devices tree/My Devices/CORE > Device data/Network Interfaces
    • Change: eth0,dhcp|eth0:0,192.168.80.1,255.255.255.0 to: eth0,dhcp|eth1,192.168.80.1,255.255.255.0
  • /etc/network/interfaces (can be edited from the launch manager).
    • Comment out eth0:0 related entries:
auto lo
        iface lo inet loopback
        address 127.0.0.1
        netmask 255.0.0.0
#
#
# Set eth0 to use DHCP to connect to cable/DSL/etc automatically.
auto eth0
        iface eth0 inet dhcp
#
#auto eth0:0
#iface eth0:0 inet static
#       address 192.168.80.1
#       netmask 255.255.255.0
#
# Set eth1 to use the internal network.
auto eth1
        iface eth1 inet static
        address 192.168.80.1
        netmask 255.255.255.0
  • Ensure /etc/default/dhcp3-server contains (only) INTERFACES="eth1" for the internal network.
  • You may need to edit /etc/iftab as well and add a line similar to the eth0 one for your new eth1 with it's own unique MAC address. See man iftab for more details on this file.
  • Web Admin: Advanced menu > Network > Network Settings (more or less optional)
  • Check the /etc/exports file, if it looks like this (Please note that these are just examples, your file will likely be somewhat different):
# /etc/exports: the access control list for filesystems which may be exported
#               to NFS clients.  See exports(5).
#
# Example for NFSv2 and NFSv3:
# /srv/homes       hostname1(rw,sync) hostname2(ro,sync)
#
# Example for NFSv4:
# /srv/nfs4        gss/krb5i(rw,sync,fsid=0,crossmnt)
# /srv/nfs4/homes  gss/krb5i(rw,sync)
