[kwlug-disc] IP addresses and gateways--my google-fu seems to be lacking

Maybe I missed something, but why are you using 192.168.10.1 with subnet
mask 255.255.255.0, when the rest of the network is 192.168.1.0?  That
".10" is throwing you off if you're using a /24 subnet.

Technically speaking, unless you use route tables something on the
192.168.10.0 subnet won't talk to something on the 192.168.1.0 if the
subnet mask is 255.255.255.0 (i.e. /24).  You could try changing everything
to SM 255.255.0.0 (/16) but that can be risky also.  Much easier if you
have all of your devices on the same 192.168.1.0 (or you could even flip
everybody over to 172.16.x.x/16, or 10.x.x.x/8)

_Ideally_ the gateway is the address of the router (the "inside" port),
usually 192.168.1.1 or .0.1.  Exceptions to this rule come when you're
running subnets all over the place, but that's probably more than you need
for your installation.
