For this chain (presumably packets inbound to the network), accept any 
packets that are part of established TCP connections (ie: a SYN packet 
for the connection has gone out from the network), or related to UDP 
packets that have gone out through the firewall.

Otherwise, reject the packet by sending back an ICMP message telling the 
remote host that communication with its intended target is 
administratively prohibited.
