[GRLUG] DD-WRT DHCP/IP address problem

[Mark Farver]

Seems odd that a "guest" network would be issuing addresses that have
the same subnet as the primary network.  It would make it a lot more
complicated to firewall the guests off from the main network.  Are you
sure that giving guests IPs from a different netblock isn't the
intended behavior?
