2 IP addresses in RH9

[Shawn McPike <smcpike sbcglobal net>]

1)  I just recently set up RH9.
2)  I have an external router/firewall that handles
one-to-one NAT on my external IP addresses (i.e.
EXTERNALIP1 --> 192.168.254.10 and EXTERNALIP2 -->
192.168.254.11).
3)  Both external IPs are registered domain names that
I own (domainname.com)
4)  OK - here's the question... both of the mentioned
internal IPs need to point to my linux machine.  I
have 1 configured so far and here is the ifconfig for
my single NIC:

eth0    Link encap:Ethernet  HWaddr 00:04:5A:64:62:51 

          inet addr:192.168.254.10 
Bcast:192.168.254.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500 
Metric:1
          RX packets:13212 errors:0 dropped:0
overruns:0 frame:0
          TX packets:10375 errors:0 dropped:0
overruns:0 carrier:0
          collisions:0 txqueuelen:100 
          RX bytes:12378958 (11.8 Mb)  TX
bytes:2735929 (2.6 Mb)
          Interrupt:11 Base address:0x4000 

5)  not sure if this helps, but here is my IP routing
table.

Destination     Gateway         Genmask         Flags 
 MSS Window  irtt Iface
192.168.254.0   0.0.0.0         255.255.255.0   U     
   0 0          0 eth0
169.254.0.0     0.0.0.0         255.255.0.0     U     
   0 0          0 eth0
127.0.0.0       0.0.0.0         255.0.0.0       U     
   0 0          0 lo
0.0.0.0         192.168.254.254 0.0.0.0         UG    
   0 0          0 eth0

6)  So (A) how do I set up 192.168.254.11 on the same
NIC??
7) And (B) I get messages on FQDN's not being
configured: i.e when I start Apache:

Starting httpd: httpd: Could not determine the
server's fully qualified domain name, using 127.0.0.1
for ServerName

Thanks in advance!
