Why FEC and SCC1 can not work at the same time?

[Rick Hunnicutt]

This looks like it may be a simple network issue. You have eth0 on the
192.168.1.X subnet. The subnet mask is set to 255.255.255.0 meaning it can
see all other 192.168.1.X IP's. eth1 is set to 192.168.2.X subnet with the
same subnet  mask so he only sees other IP's on the 192.168.2.X subnet. Your
gateway is 192.168.2.1 for eth1. Is this gateway able to reach both
networks? Have you tried making these on the same network (192.168.1.X) and
trying to ping them?
