IP address Red Hat ES release 2.1 (Panama)

[olaritter]

hello

i have a box with RH Enterprise Linux ES 2.1 (Panama) with private address. and is directly connected to a pix firewall with public address. when i ping my pix firewall, I receive info that my address is public one, within the same network range which the pix address i'm pinging belongs to. that is understandable and quite logical. otherwise i wont be able to ping it.
1. the point is i didnt configure it; nor did i the pix.
2. the pix was double checked for eventual nat-ing, but was told there is no nat-ing (ios 6.1)
3. when i navigate to /etc/sysconfig/network-scripts and /etc/sysconfig/network, i do check the content of EACH file to make myself absolutely sure but I still cannot see a public ip address.
4. ifconfig gives no address assigned on my nic. no double-colons files ifcfg-eth0:0 or ifcfg-eth0:1 in network-scripts or something that will point to an alias of my nic with different static ip address.
5. it is Red Hat ES so I'm not sure if this is all I need to look for a queue/lead so I can resolve it. any other places to look for configuration? I must change the public address! thats the point;

and forgot: i can access the red hat es 2.1 by https directly by the public ip address. tracerouting from the red hat es 2.1 towards outside (for example google) is forbidden on the pix firewall - wanted to see in how many hops i do get to the pix firewall. maybe some device is in between, but still, i checked the route table nothing; the pix itself is configured as default gw.

thanks!
