Interesting -- I hadn't heard of such a thing before (may well be a standard thing -- the fact that I don't know about it doesn't mean a thing).
Anyway -- how can one go about setting up such a block? Does it depend on the router (even as to whether it's possible)?
If it's a Linux router, http://www.ecst.csuchico.edu/~dranch/LINUX/ipmasq/examples/rc.firewall-iptables-stronger suggests a way to do something similar using the "--state ESTABLISHED,RELATED" option to iptables.
