RTEMS BOOTP and Linksys routers

I have rtems with networking support running on one of our instruments.
When I connect the instrument to our company network, I get a valid IP
address and everything seems to be working fine. I then connected the
instrument to a Linksys router ( BEFSR41 ) and I cannot get the linksys
rounter to give me a bootp reply packet.  Instead I get a packet that
contains other packet data. Has anyone tried to connect the RTEMS stack
to a Linksys router?  Here is the packet data I am receiving from the
router.

Bootpc testing starting
bootpc hw address is 0:50:c2:3d:b0:32
