sounds like you did not add a proper default route, or there 
is a deeper netmask issue.

File should look something like this (I have trimmed lots 
out):

[herrold at ftp etc]$ grep -v ^# dhcpd.conf
ddns-update-style none ;
server-identifier ftp.eleven.lan ;
option domain-name-servers 10.16.11.253, 66.195.224.112 ;
option time-offset 300;
default-lease-time 600;
max-lease-time 14400;
option option-128 code 128 = string;
option option-129 code 129 = text;
shared-network ELEVEN-LAN {
option routers 10.16.11.1; # router being our router;
option domain-name "eleven.lan";
option subnet-mask 255.255.255.0;
allow booting;
allow bootp;
  subnet 10.16.11.0 netmask 255.255.255.0 {
   pool {
    range 172.16.11.2 172.16.11.98 ;
    authoritative ;
    allow unknown-clients;
   }
  }
}
