I don't see the relevance of that.
I never said I had or didn't have any iptables rules.
I'm simply observing that I do not have the specified setting
and I can access my server from my LAN,
therefore the setting cannot be essential for this purpose.

I can access the server because I have
	loc             $FW             ACCEPT
in /etc/shorewall/policy;
but that is not really relevant to the point at issue.
