Debian Install on O2 R5000 tftp timeout troubles

[Alex <slifox@gmail.com>]

Hello,
I've recently been trying to install debian on an O2 (R5000), but am
having issues with tftp timing out. I've followed every
debian-on-o2/indy tutorial out there and I always get the same
problem.

The main tutorial I've been using is
http://www.pvv.org/~pladsen/Indy/HOWTO.html and
http://www.cyrius.com/debian/o2/

I've set everything up properly on my tftpd machine. Using tftp from
another computer and trying to get /tftpboot/tftpboot.img works fine.
However, when I type "bootp(): tftpboot.img" (and I've tried every
combination of "bootp()" commands and arguments) on the O2 box, it
hangs after setting $netaddr to its assigned IP address (according to
dhcpd.conf). The tftpd log says that its trying to send the file, but
is timing out (all important file contents are listed below).

# cat /proc/sys/net/ipv4/ip_no_pmtu_disc 
1
# cat /proc/sys/net/ipv4/ip_local_port_range 
2048    32767

Any help would be very appreciated!
Thanks
