  Don't arbitrarily drop all ICMP, bad idea, breaks a few things.

  Couldn't the 'full ip conntrack table' problem be solved by echo'ing a
bigger number into /proc/sys/net/ipv4/ip_conntrack_max ?

	root@jimblewix:/proc/sys/net/ipv4;
	23:48:19 0$ echo 32768 > ip_conntrack_max=20

certainly changes it here.
