I guess I've got the hat on :)

The got to the right place :)

I've added a reference to the firewalls section, but "options GATEWAY"
is no longer required.  If you want to forward packets (this is
what options gateway does), you just need to set the sysconfig
(now rc.conf) variable.  In your suggested files below, the
"enable proxy" circumvents the need for forwarding (enable proxy
does the forwarding inside ppp).

Added.

Most of this stuff has turned into links to other bits of the
handbook.

Should do.  Thanks for your contribution.
