I've noticed that a lot of people use the 192.168.X.X subnet for internal networks, is this (and the less-used 10-series) a requirement of some RFC, or a recommendation that has become tradition? We are using a completely different subnet, something similar to (for example) 42.127.129.X to further obfuscate the internal network from outside. This, and many other examples, produces a class-A subnet mask (some produce a class-B) when entered in WinXP's TCP/IP dialog, although the actual mask we use with it is class-C. Is this a no-no? Will it break our server's IPTables when communicating with it? Am I in for a lot of trouble? The addresses don't seem to cause any problems, but I don't want this to jump up and bite us in the bottom sometime down the road. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Paul Blondé
