do a `depmod -a` as root and this will go away.

I'm guessing your route to whatever IP address eth0 has is not set correctly.

This is normal behaviour.
To change the default configuration, edit /etc/sysctl.conf .
you'll find the line `net.ipv4.ip_forward = 1` which determines
default behaviour. Edit this line and you shouldn't have any more
problems.
BTW, you don't have to reboot a Linux system for this type of change
to have effect.

Again, this is standard behaviour.
Change the config files to change it.
This should go in /etc/sysconfig/network,
/etc/sysconfig/network-scripts/ifcfg-eth0 or, in the worst of cases,
in /etc/rc.d/rc.local
