Route internet address to specific network interface

Question

I have two network interface wired (eth0) which is filterd by proxy the other one is wireless (wlan0) which is free I need to make specific url's to wireless interface to avoid the proxy.

Answer 1

Add a route with a lower cost (e.g. lower hop-count or other appropriate metric)

E.g. route add -host 1.2.3.4 dev eth1 metric 1 (untested)

Answer 2

I suppose that you want that all your request to lan goes to eth0, and all other requests (internet addresses) are for wlan0.

Everything depend on the configuration of your network. You need to know the ip of your lan gateway. You can obtain it with the following command:

route

You must play with your route table. My solution for the same problem (eth0/ppp0) is: 1. Delete default gateway:

route del default gw

2. Add a default gw that point to wlan0:

route add default gw youripwlan0

3. Add a route rule that send all lan requests to eth0:

route add -net 192.168.1.0 netmask 255.255.255.0 dev eth0

Where you must replace -net and netmask with values that fit your lan configuration. 4. Then add another gateway that is used for the requests done inside the lan:

route add -net 192.168.1.0 netmask 255.255.255.0  gw 192.168.1.1

Again -net netmask and gw must be changed according to your configuration. And maybe you want to edit the /etc/resolv.conf file to add a DNS server reachable from the wlan network.
