I see at least one problem with this packet: (This is the bootp reply
from the bootp server)

The problem is the server is assigning a subnet 80 address to bob-pc
(132.241.80.11, actually).  This is why bob-pc is not receiving the
reply.  The router will send the packet to its subnet 80 interface.
Look at the arp cache for 132.241.80.11 on the router.  You will find
it points to 0207:0108:6be4.

Take a look at ther servers bootp config file.
