network manager with two interfaces

[Bo Forslund <bo forslund abc se>]

I tried to use network manager with two interfaces and ip masquerade and 
could not get it working.

Eth0 is the internet interface connected with dhcp.

eth1 is manually set to 192.168.0.1 etc...

This couldn't be set with the nm-applet.

I had to hand edit /etc/udev/rules.d/70-persistent-net.rules and 
/etc/network/interfaces.
This was done with an out of the box installation of debian 6.0.6. It 
seems like the install process randomly sets the network cards to 
eth0/eth1 from one install to another on the same computer. (I had to 
abort the first install attempt for some reason i don't remember. The 
next install attempt eth0 was eth1 and eth1 was eth0).

After hand editing the files mentioned above the system works but the 
nm-applet says "enheten hanteras inte" might translate to the unit is 
not handled.

eth0
enheten hanteras inte
(unit not handled)

eth1
enheten hanteras inte
(unit not handled)

The system works. Ip-masquerade works. Is it possible to get the 
nm-applet telling that ip-masquerade is up and working?

The contents of the files /etc/udev/rules.d/70-persistent-net.rules and 
/etc/network/interfaces comes below
