While it would seem that this would work fine on the LAN side, what would happen if you actually tried to a site that has that same IP? You would type in www.blahblah.com
, the DNS server would hand you back the IP of the server (which is the same as one of your machines) and you would not be able to connect because you would be trying to connect to a machine on your network. In case you were wondering, the range you chose is used by Singtel in Japan according to a whois query.
I bet if you tried setting the LAN side DHCP range the same as a site you visit often, I'm pretty sure you won't be able to connect to that site anymore (even though I havent' tried this yet).
Therefore, it's best you either use the ranges glc described in his earlier post instead.
