I am having some problems in relation to speed of traffic of packages when 
using iptables.
The problem is the following:
When there is not any iptables´ rules, a inner connection through FTP is less 
than 1 second long to be made.
With the rules that I did, a inner connection delay more than 7 seconds.
    
Is that normal or are my rules wrong?
  
regards,
