Network problems

[E-Jey]

I have the following situation right now: an ubuntu edy eft machine with two NICs (eth2 and eth3). One is configured with DHCP and the other has a static ip (223.0.157.3 255.255.255.240) and is connected to a router.
When I ping 223.0.157.2 (which is in the same subnet) everything works fine. But when I ping to 223.0.157.19 (which is in an other subnet and connected through the router), my computer tries to find that machine through eth2 (which is configured via DHCP). How can I solve this?

Aren't both 223.0.157.2 and 223.0.157.19 in the same subnet? Am I missing something?

Yes, you are missing something. The strange thing is that when I tracert the 223.0.157.19, my computer tries to find that PC trought eth2. The default gateways are set oke, but still he's searching on the wrong interface.

Can you post the output of:
route
and
ifconfig
