packet pass through vs ftp -- performance weirdity

[RYAN vAN GINNEKEN]

Happened to me once needed to set the the speed of the nic card in 
rc.conf can not remember how to do it but it is in the man rc.conf page 
and solved my similar problem.  Looks something like this if i can recall

ifconfig_xl0="inet 209.155.173.22 something about manually setting the 
speed and mode of the card "

for me it had to do with the card not negotiating it parameters properly 
and i had to beat it into submission with manual overrides.  glanced 
through the rc.conf man page but it is to long for me deal with right 
now the setting are in there somewhere.
