That sort of thing is an old complaint, and the solution is to manually
configure your network so that certain hardware is tied to a particular
interface by the MAC address.

For example, on one of my computers:

[tim@gonzales ~]$ cat /etc/sysconfig/networking/devices/ifcfg-eth0 
# Silicon Integrated Systems [SiS] SiS900 PCI Fast Ethernet
DEVICE=eth0
BOOTPROTO=dhcp
HWADDR=00:11:2f:f4:57:8f
ONBOOT=yes
NM_CONTROLLED=yes
DHCP_HOSTNAME=gonzales
TYPE=Ethernet
USERCTL=yes
PEERDNS=yes
IPV6INIT=no

Notice the HWADDR line, after the equals sign is the MAC of that
particular interface.  Play around with the ifconfig command to find the
MACs of your interfaces.

Don't send private replies to my address, the mailbox is ignored.  I
read messages from the public lists.
