[ubuntu-cloud] Introducing myself and first question

Hello Torsten

========== front end 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 eth1

auto eth0
iface eth0 inet static
    address 192.168.64.1

auto br0
iface br0 inet static
    address 192.168.64.2
    netmask 255.255.255.0
    network 192.168.64.0

========================== NC ip show
=========================================================
3: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state
UNKNOWN
    link/ether bc:ae:c5:94:f4:db brd ff:ff:ff:ff:ff:ff
    inet 192.168.64.2/24 brd 192.168.64.255 scope global br0

       valid_lft forever preferred_lft forever
===========================================================================================

The NC machine is able to ping and ssh the frontend (192.168.1.64) but
doesn't reach the client (192.168.1.127 that is also the gateway to
reach internet)

The path should be: NC (192.168.64.2) --> FrontEnd (eth0
192.168.64.1)--> FrontEnd (eth1 192.168.1.127) --> client (eth0
192.168.1.127) --> client (wlan0 10.94.169.14) -->ISP wireless router
(10.94.169.1) --> ISP and Internet

On the client routing and maquerading is done with shorewall

Thanks
    Mirto
