VNC on iMac G4, 10.4.11
* On the Westell modem, made sure the firewall was off and forwarded global-to-local ports 5500, 5800, and 5900 using TCP.
* On the Netgear router, forwarded port 5900 to the iMac's local IP.
* In Sharing/Services, turned on Personal File Sharing, Personal Web Sharing, and Apple Remote Desktop. For Apple Remote Desktop, I have 'Guests may request permission to control screen' and 'VNC' viewers may control screen with password:' checked on the Access Privileges panel.
* In Sharing/Firewall, I created a new service ("VNC") for TCP ports 5900-5902 and UDP port 5900. I also have 'Block UDP Traffic' unchecked.
When I check this at gotomyvnc.com, it reports that nothing is responding. When I check port 5900 at canyouseeme.org, it says the connection was refused. I've tried forwarding ports 5500 and 5800 on the Netgear router and turning of the OS X firewall completely, but still get the same results.
Any help or advice would be appreciated - thanks!
