I think tri may be confusing 'subnet' (or network) with 'subnet mask'.
The two NICs need to be in different subnets, however the subnet masks for
the two networks may be the same.
eg.
10.0.0.0 is a network address. If I apply the standard subnet mask for this
class address, 255.0.0.0 I can have hosts at addresses from 10.0.0.1 to
10.255.255.254.
but then we throw away classic classful addressing. When SBS4 came out MS
decided to use 10.0.0.0/24 (/24 is just a quick way of writing
255.255.255.0, 24 bits of mask)
using a 24 bit mask 10.0.0.0 is a different network to 10.0.1.0, they are in
different subnets.
Even though classless addressing has been acceptable for some time I prefer
to use proper classful addressing, mainly because I've observed some
hardware which doesn't operate correctly if a, for example, class c mask is
applied to a class a network.
In SBSville we are unlikely to need more than 254 host addresses so a /24
mask is normal. When using a 24 bit mask in a private IP range it is normal
to use 192.168.x.y, where x is selected arbitrarily from 0-255. This is a
standard Class C network.
(coincidentally, I looked up the assigned 192.whatever networks
http://www.flumps.org/ip/c/192/192.html)
SO, if you use 192.168.0.0/24 for one interface and 192.168.1.0/24 for the
other you should be considered close to 'best practice'.
NOTE: using 192.168.24.0/24 and 192.168.56.0/24 is no more or less better.
HECK, one day you might need a large number of routers and many local PC's.
It's just as valid to use:
192.168.11.0/24 for the external and
10.0.0.0/8 for your LAN.
but I'd be more likely to use a /24 both sides.
