[gentoo-user] configure wlan0 route metric

[deadeyes]

Hi all,

For my home network I am generally using wireless to get connected to the
network and the internet.

However for copying some large files I use the wire.

That means I get 2 IPs in the same range.
And both interfaces get the same metric : 0.

I found out I can modify the metric for the default route using metric_wlan0.
Code:

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 wlan0
0.0.0.0         192.168.1.1     0.0.0.0         UG    2      0        0 eth0
0.0.0.0         192.168.1.1     0.0.0.0         UG    100    0        0 wlan0

(this is not the full routing table)
However this changes the metric of the default route.
Not of the route that is specifically for the local network.
of course I can do this manually.
However that is alot of hassle and seems to be something that should be
configurable use files.

Does anyone knows how I can accomplish this? Or how I can change the metric for
each route for the wlan0 interface?

Thanks in advance!
