Salut,
I have a question about subnetting. I want to build following network:
Internet
|
|
Router
|
eth0| eth1
Firewall--------Intranet
eth2|
|
|
DMZ
Where the intranet will be masqueraded by the firewall, but the DMZ
(with services like www, smtp, etc..) has global ip's. So eth0 needs a
global ip for correct masquerading, router needs a global ip, eth2 needs a
global ip for DMZ. If I do not build two subnet (router, eth0 of firewall
and dmz, eth2 of firewall) the routing of the firewall will not work,
because dmz and router are in the same subnet. That is why I made two
subnet.
I can use 128 global ips, but with my solution 62 ips (64 minus router
minus eth0 of firewall) are lost, because I have not managed to build
asymmetric subnet.
Is there any other possibility? Like asymmetric subnetting?
I have read lots of HOWTOS, but none matched my problem, they were all
building symmetric subnets.
Thanks a lot for every helping hand!
Best regards,
Christoph

The primary purpose of the DATA statement is to give names to
constants; instead of referring to pi as 3.141592653589793 at every
appearance, the variable PI can be given that value with a DATA
statement and used instead of the longer form of the constant. This
also simplifies modifying the program, should the value of pi change.
