Potential errors on Simple Stateful Firewall Wiki page?

Question

Reading through the Simple Stateful Firewall Wiki page I think I see a few errors.  I'm willing to make the changes myself but before I do and end up creating a real error I'd like some confirmation from folks more familiar with iptables than I am.
I think the first errors are that the wiki page indicates this
iptables -N TCP
iptables -N UDP
I think it should really be
iptables -N OPEN-TCP
iptables -N OPEN-UDP
The other error I think I see is this
iptables -A INPUT -p icmp --icmp-type echo-request -m recent --name ping_limiter --hitcount 6 --seconds 4 -j DROP
I think that one should be
iptables -A INPUT -p icmp --icmp-type echo-request -m recent --name ping_limiter --update --hitcount 6 --seconds 4 -j DROP
Thanks.

Answer 1

The wiki page says:
Warning: This is the step where you will be locked out if you are logged in via SSH. Therefore do this step following your rule regarding port 22 (or whatever port you're using for SSH) to prevent being locked out.
Note the pink background, and the boldness. Not bold enough?
