Two network cards configuration

Hi

I have problem with my network - I have two network cards and it seems they can't live both but I need them both so:
1st card (rtl8139) is connected to cable modem and gets ip by DHCP (eth0="dhcp" in rc.conf)
2nd card (nv forcedeth) is connected to router and gets ip by DHCP too (eth1="dhcp")

When I start them both -> 1st and 2nd card gets good IP by DHCP but when I want to ping google.com for example packet is lost.

What I want ? I want to use my eth0 (1st card) for internet and my 2nd card for local network.

##EDIT##

My resolv.conf is 192.168.1.1 but I need DNS from 1st interface -> how to do this?

Messy setup IMO, but anyway....

Your faulty resolv.conf is the reason you can't ping google. Edit it manually as required, and then use the -R flag in /etc/conf.d/dhcpcd to prevent it being overwritten. DHCP on both interfaces will probably cause routing issues as well, in which case you will need the -G flag.
