[Launchpad Bug Tracker]

Binary package hint: gnome-nettool

I have configuration with follow iptables
   iptables --flush                         - Flush all the rules in filter and nat tables
   iptables --table nat --flush
   iptables --delete-chain                  - Delete all chains that are not in default filter and nat table
   iptables --table nat --delete-chain

   # Set up IP FORWARDing and Masquerading
   iptables --table nat --append POSTROUTING --out-interface ppp0 -j MASQUERADE
   iptables --append FORWARD --in-interface eth0 -j ACCEPT         - Assuming one NIC to local LAN

And follow /etc/network/interfaces:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto ppp0
iface ppp0 inet wvdial

#The secondary network interface
auto eth0
iface eth0 inet dhcp

#The thirdy network interface
auto eth1
iface eth1 inet dhcp

My ifconfig is :

eth0      Link encap:Ethernet  HWaddr 00:50:8d:94:43:8a  
          inet6 addr: fe80::250:8dff:fe94:438a/64 Scope:Link

But after add in /etc/network/interfaces like primary interface ppp0 now not get automatically ip via dhcpfor eth0 interface.

Somebody can help me?

Kind Regards
Vincenzo
