Your subnet math is correct, but as good practice, you want to NOT use
the low and high networks (.0 and .193).  The reason being is that those
networks contain the network name for 192.168.10 and the broadcast
number for that network.  You CAN do it, but even Cisco recommends
avoiding it when possible.  But you are right on the money w/ the masks.
Good Luck!

I have two LANS at different locations.
LAN A has IP numbers in the range of 192.168.10.1-20
LAN B has IP numbers in the range of 192.168.10.99-120
I want to connect them using a VPN, but that requires that they be on 
separate subnets.

I figure I can use for LAN A:
192.168.10.0  netmask 255.255.255.192
and for LAN B:
192.168.10.64 netmask 255.255.255.192

BUT, being a neophyte at network topology, I would like someone who
knows 
more than I to confirm or to show me the errors of my ways.  I don't
want to 
put these into the routers (Netgear FVS 318) and lock myself out (again
!)
