The thing about UDP packets is that they're "connectionless" which means you 
don't have to establish a connection like TCP; it's just there. 

Now, Jackie's question about removing "them." You can't remove UDP support as 
it IS used by many things including DNS lookups, so, w/out UDP support, you 
couldn't do anything unless you relied entirely on IP addys.

As for your firewall, I hope you're not denying ALL UDP packets! I'm not sure 
I understand someone asking to "Drop" a UDP packet on your system, that 
doesn't make sense. You can't drop something and expect something else to 
catch it if it's not listening.

In conclusion, UDP packets pose no harm, they can't crash your system. So, 
there's really no reason to deny UDP packets.
