[network manger] : overriding default IPv4 routing.

[Manoj Manthena <manoj manthena tcs com>]

Hi All,

I have the following problem scenario.

1) Currently connected my desktop to a wireless access point.(active connection is wlan0)

2) As soon as I connect a usb tethered device/ethernet , network manager selects usb0/eth0 as the default for IPv4 routing and DNS.

Currently using 0.9.4.1-0ubuntu2.3 of network manager.

I would like to override this behavior. Please let me know how I could do that.

Is there any [keyfile] tag which can be added in NetworkManager.conf so that my default IPv4 device is always wlan0?

I came across 

[ipv4]

never-default=true

but is there anything like 

[ipv4]

default=true

so that i will add it under my /etc/NetworkManager/system-connections/ configurations 

Regards,

Manoj
