SSH Forwarding

[Geoff Sweet <wayloud2@attbi.com>]

I have read heaps on the internet regarding TCP forwarding in SSH, but
for the life of me I can't figure out what I need to set to make a
particular SSH forward get created at boot time and stay that way.  I
want to create a SSH forward for port 3389 so that I can safely terminal
serve into my domain.  I am currently operating OBSD 2.9.  Do I need to
modify the ssh_config file or the sshd_config file?  Or perhaps
neither?  Thank you for you input.
