[LARTC] Asyncronous Connection.

[Rio Martin.]

Hi folks,
I need to develop asyncronous connection just like in DVB Satellite One Way 
Service, in my network. Incoming traffic and Outgoing traffic flowing through 
different link and interface.

Here i describe you more,

Existing system:
[ Router A ]
      eth0 : 192.168.0.1
          |
          |
          |
          |
      eth0 : 192.168.0.2
[ Router B ]

Router A and Router B on the same network 192.168.0.0/30
Router A set route to network 192.168.1.0/24 goes to 192.168.0.2

And my plan is to split the system like this,

Split system:
[ Router A ] 
eth0 : 192.168.0.1
 |  eth1
 |     ||
 |     ||
 |     ||
 |     ||
 |  eth1
eth0 : 192.168.0.2
[ Router B ]

Incoming traffic to 192.168.1.0/24 from Router A to Router B goes through eth1 
interface.
Outgoing traffic to 192.168.1.0/24 from Router B to Router A goes through eth0 
interface.

Is this make sense with just using iproute only ? Please let me know how. 
Thanks.

Regards,
Rio Martin.
