firewall with real ip's and local ip's

[Anders Gj�re]

hi.
im suposed to set up a firewall for a shell server.


it should be something like this


internet<-->real ip's<-->(firewall)<-->local ip's<-->(shellserver)


the shellserver has 60 ip's and should be mapped up like this. (correct
me if im wrong at any point)

213.151.128.0 = 192.168.0.0
213.151.128.1 = 192.168.0.1
213.151.128.2 = 192.168.0.2
213.151.128.3 = 192.168.0.3
213.151.128.4 = 192.168.0.4
and so on



is this a good solution?
the firewall is running 2.4.5 and iptables



mvh
