Are you saying you must have the setting you mention in /etc/sysctl.conf ? That cannot be true, as I can access my server and I don't have your entry.

Check your iptables rules. Maybe there are no INPUT rules to access your gateway via internal nic.

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.
