[NTLUG:Discuss] Firewalling Using RedHat

[Tim Willis]

Here is my situation.  I've just added an additional NIC to my RedHat
7.2 box.  It recognized the card and I configured it with the correct IP
and subnet, and then the boot process continued.

However, upon doing ifconfig, I only get the lo interface paramaters.
I've had to re-set the network configuration for my internal card (eth0)
each time I've re-booted.  

Looking in the GNOME Network configuration utility I've found that both
cards are listed, and also, they are configured with the proper IP,
netmask, and gateway.  However, like above, if I run ifconfig, I only
get the parameters for lo.  After I do ifconfig eth0 192.168.254.2
netmask 255.255.0.0 / route add default gateway 192.168.254.1, I can get
the parameters for eth0 (in addition to lo).  If I try to set the IP and
netmask for eth1, the message is: 

SIOCSIFADDR: No Such Device
eth1: No such device
SIOCSIFNETMASK: No Such Device 

Do I need to add eth1 somehow?  Why Do I have to continually re-do the
ip/netmask on the internal card each time I re-boot?

Thanks
