Hmmm.  I'm not sure why the router is doing a BOOTP request, but
laying that aside, you have to do more than turn the daemon on to 
get BOOTP to work.  When a BOOTP client comes up and does a request
for an IP address, the BOOTP server looks in its config file, usually
/etc/bootptab, for the MAC address of the client.  If it finds the
address there, it returns the associated IP address - otherwise the
server does nothing.  Look at the man pages for bootptab for config
information.  You might also want to check out DHCP rather than 
BOOTP if your router can use it.
