Confused about routing

[ec734]

Hi,
I've been using VNC for years and just found Ultravnc and love the fact I can finally do file transfers.

I'm setting up a new network at the office and want to connect to any workstation from home, but I'm confused about routing. I have loaded Ultravnc on several workstations and works fine in the office using PC names or IP address(DCHP is being used, so IPs are dynamic)

I have a static ip on a Netopia DSL router, that I can ping from home. Here's where I'm stuck. If I try to connect to {public IP}, how does the router know which workstation I want to connect to? Is this where I have to use ports? Do I connect to {public IP/port} and then configure the router to determine which workstation by the port. In that case, how do I set up a path in the router which links the port number to a dynamic IP.

I'm probably dancing around an easy solution, but I'm stumped.

Any help appreciated

Thanks

The good solution is installing repeater as mode I at your office so you need only forward 1 ports even you have a lots of computers at your office
http://prdownloads.sourceforge.net/ultr ... p?download

let all vncserver default port 5900

only at your office
DSL Netopia router ---> repeater internal redirect --> port vncserver
port static public ip --> port hostname_repeater --> port vncserver
5900 static public ip --> 5901 hostname_repeater --> 5900 vncserver


schematic (depend of upstream bandwith of office)

one client can control many different vncserver as same time
viewerA --> home/NAT router --> Internet --> office/NAT router -- repeater ---> vncserverA
viewerA --> home/NAT router --> Internet --> office/NAT router -- repeater ---> vncserverB
viewerA --> home/NAT router --> Internet --> office/NAT router -- repeater ---> vncserverC

or/and

every vncviewer remote control an different vncserver
viewerA --> home/NAT router --> Internet --> office/NAT router -- repeater ---> vncserverA
viewerB --> home/NAT router --> Internet --> office/NAT router -- repeater ---> vncserverB
viewerC --> home/NAT router --> Internet --> office/NAT router -- repeater ---> vncserverC

or/and

all viewers watch same content !
viewerA --> home/NAT router --> Internet --> office/NAT router -- repeater ---> vncserverA
viewerB --> home/NAT router --> Internet --> office/NAT router -- repeater ---> vncserverA
viewerC --> home/NAT router --> Internet --> office/NAT router -- repeater ---> vncserverA


just remember your static public IP address for reach your office/NAT router then office/NAT router redirect to your internal hostname address of your repeater and repeater redirect your request to the hostname of your vncserver your requested from viewer

EC:

Heya. At the risk of self-promoting, EchoVNC is a much easier solution. Just install it alongside your target VNC servers, and use it to login to a common echoServer. Login with names like "PC-1", "PC-2", "PC-99", etc. Then when you login to the same echoServer from anywhere else, you can easily connect to "PC-1", "PC-2", etc, regardless of IP addresses and without any port-forwarding.

Hope it helps!
