[Bug 788301] Re: Networking fails with two interfaces on the same network

[blue balls]

The problem appears on Ubuntu 10.04.

  I also tested this in Ubuntu 11.04 on another computer with two
interfaces (eth0 and wlan0) and the same problem occurs.

Title:
  Networking fails with two interfaces on the same network

Status in “ifupdown” package in Ubuntu:
  New

Bug description:
  Binary package hint: ifupdown

   Summary: when two network interfaces on the same computer are
  configured on the same network, the networking fails.

    Details: I have two network interfaces eth0 and eth1 which have static addresses: 192.168.1.2 and 192.168.1.3.
    The gateway is a home router which has the address 192.168.1.1.
    When both interfaces are brought up with "ifup", I cannot connect to the Internet. When only the first on is "up" and the other one is "down", the connection to the Internet works well.
