TFTPD timeout

[Maxim V Tretjyakov]

Hello freebsd-stable,

  tftp-client connects to server from local ethernet network or localhost and
  recieves timeout any time. I post it there:
load# tftp localhost
tftp> get pxeboot 
Transfer timed out.

About firewall, here are rules. rl0 sees internal network and rl1 -
external. As i see it isn't drop tftp packets.
load# ipfw show

At all, here is uname -a of a machine with tftpd:
load# uname -a
FreeBSD load.dom-sp.ru 4.10-STABLE FreeBSD 4.10-STABLE #6: Fri Jul 23 16:41:07 YEKST 2004     knyaz at kl-nat.dom-sp.ru:/usr/src/sys/compile/MYCONF  i386

Also, tcpdump sees repeating RRQ requests, when i try to get file from
my workstation:
load# tcpdump port tftp
tcpdump: listening on rl0
