where's the "VNC through a Linksys firewall" FAQ?

[msledge@bellsouth.net]

i've searched through some of the list and read the documentation but for whatever reason i must be missing something.  i see in the documentation that you need to forward port "5900+N" for standard VNC and port "5800+N" for web/java VNC.  i know how to forward and enable ports b/c i have a web and ftp server running and can get to those 2 services fine.  i have a Linksys router.  i just did a standard install of VNC server.  i didn't change any settings/options.  i can get to it fine from within my home network (192.168.1.x).  i forwarded port 5900 (TCP only) on the router to the machine where VNC server is running.  from work i try to hit my public static IP with VNC viewer (the same version i'm using successfully within my home network) and i get "unable to connect to hose: Connection timed out (10060).

any ideas what i'm missing here?
