Looks that way.  I find that relatively reassuring.  No "linux magic" 
involved.  But then, if you didn't set that up, who did?

I'd recommend either setting the rules up in a "rules-eth0" or such file 
in /etc/sysconfig/network-scripts, or using shorewall.  Inventing your 
own system is workable, but as you've found, they tend not to be 
documented well which leads future admins (or even future you) to wonder 
how things work.  Use the facilities available rather than fighting them.
