hi all,
I be very gratefully for any help..
my firewall has 2 nic's the external one's ip 194.125.213....  but behind
the firewall I have a proxy server and an email server with ip's 192.0.0.106
and 192.0.0.253. I know I need to use DNAT and SNAT to send internet packets
to them but i do not know how to add aliases to  the eth0 so that i can
route packets to my firewall and then DNAT them on...
does any one know how to use this "ip add address" command   ( maybe even a
example or two)
thanx for all your help
