I'm sure that this is blindingly obvious, but I have not been able to find any
references to it...
I have a class C address for my network - As part of my firewall I will have a
dual homed sparc 5 running Solaris 2.5. I want to forward packets from one
interface to the other - am I allowed to use netmask 255.255.255.0 with both
interfaces in the same subnet e.g.
192.100.100.1 and the other on 192.100.100.2
I have tried to set routing up for this up and failed so the question is
Do I have to subnet a class C address to achieve packet forwarding or is there
some trick in the routing that I am missing??
All the references on this soft of setup assume that you are doing packet
forwarding from something like 192.100.100.1 to 192.100.99.1, but I only have a
class C from my ISP and cannot affort to loose the half my IP addresses that
subnetting would cause.
Paul.
