It worked.

There are a lot of website guides to Linux homenetworking, some going back 
as far as tldp days (late 1990s, early 2000s). Understandably, there is no 
one that presents itself as being authoritative.

Rebuilding a CentOS box is an occasional endeavour, not a weekly one. So 
the reliance is on the informational sources that are there (some of which 
do recommend hacking rc.local or /etc/init.d/iptables), memory, and 
trial-and-error (typos and misspecified NICs can become time-sinks).
