Hello people,
I tried to deal with this problem myself for quite a while, but I failed, nothing helped, so I am here for your help.
I need to share Internet from WIMAX dongle and still be able to access the home network from the same computer.
Here is the scheme how it is right now.

The red line is on the different sub-net.
I use Lubuntu 12.04
Basically what I did was:
1. Automatically connected to Eth0
2. Shared my connection trough Eth1
3. Connected Eth1 to router Internet socket
4. Connected router LAN to Eth2
The thing is that my configuration works for a while and then crashes.
Usually all of the computers connected to router works fine and can access
the internet until I connect a cable from router LAN to main computer Eth2 (to access the home network).
Then sometimes, for a while I can access the internet and home network too.
But after some time none of the computers nor the router can access the internet.
In my opinion what I need is to bridge Eth0 and Eth1. And make the main computer access the internet from Eth2. I tried to do that using brctl, but I failed. Maybe I am missing some steps.
[CODE]~$ ifconfig
