you didn't describe your lan setup. judging from you post i'd say you
have only 1 subnet and have mistakenly used values from a different
subnet for some of your options.
if this is the case then making the changes noted below may help

# your broadcast address needs to be in the same subnet as the
assigned ip address
option broadcast-address 192.168.2.255;

# this should probably be the same as the gateway on the dhcpd server
("routers" in dhcpd.conf == default gateway in interfaces file)
# and again, it needs to be on the same subnet
option routers 192.168.2.1;
