I believe the original poster was specifically requesting how to increase the 
File descriptor limits (ulimit -n) past 65k.  This is where the limitation 
would come in most likely for connections he is talking about.  

As someone else said, probably not the best place for this, however you can 
look at /etc/security/limits.conf and play with soft and hard nofile limits.  
Try unlimited maybe.

As long as you're not connecting to the same destination IP/port pair, the same 
source IP/port pair can be reused. So even for outgoing connections there is 
virtually no limit.
