Why not block everything, then just let the traffic that you want go thru? 
That is the basic things that people do with firewall / ip tables anyway. If 
you do it that way, then you don't need to know specifically how to block 
this or that, because you block everything, except for certain traffic that 
you know you want, ie, ssh if you run ssh server, http (port 80) if you run 
webserver, etc.
