That's not much to go on. The output of "ip addr show" and "ip route
show" might help you figure out what's going on. Do your interfaces
have the expected names? Do they have the expected IP addresses?
One thing that might be problematic is that there are multiple systems
that attempt to maintain consistent interface names. If your interface
names are not what you expect, you might need to look at
/etc/udev/rules.d/70-persistent-net.rules where there may be additional
rules mapping specific MAC addresses to an interface name.
