Networking between two PC with both having two Ethernet port

I have two PC with FC2. Each PC has two Ethernet ports. eth0 is 100 MBit
at both PC whereby eth1 can use 1GBit. I can establish the following
connections:
eth0 <-> eth0
eth0 <-> eth1

but I can not ping between the two eth1s.

I configured
PC1:
ifconfig eth0 192.168.100.3
ifconfig eth1 192.168.200.3
ifconfig eth0 netmask 255.255.255.0
ifconfig eth1 netmask 255.255.255.0

PC2:
ifconfig eth0 192.168.100.2
ifconfig eth1 192.168.200.2
ifconfig eth0 netmask 255.255.255.0
ifconfig eth1 netmask 255.255.255.0

Both route and iptables show nothing suspicious. What can I do?

> eth0 <-> eth0
> eth0 <-> eth1
My off-the-cuff answer is that if "ping 192.168.200.2" really does what
you say, namely sends traffic with src=192.168.100.3 and
dst=192.168.200.2, then something is wrong.

How are you distinguishing between this and eth0 <-> eth1 ?

Don't keep us in the dark. Show us the routing table.

Exactly, show us 'netstat -rn' or you'll just waste your and our
time.

That was it. The cable was not crossed.
