I believe that Solaris will only let you adjust the range, not specify on a per port basis. You can see the smallest (default 1024) using:

ndd -get /dev/tcp tcp_smallest_nonpriv_port

You can change it using:

ndd -set /dev/tcp tcp_smallest_nonpriv_port some#

I found a nice treatise on the subject at:
