RealVNC and Routers

Ok, here's my question:
I have a customer with realvnc server on their computer.  All of the defaults are set.  They have an inside local address of 192.168.1.10 and an inside global address of 67.184.75.227.  The customer had a Linksys Wireless router, but is directly cabled to the router.   When I open realvnc viewer, which address do I put in?  Also, does the server program have to have a different server # since it is behind a router.  Shed some light on this please.  I'm trying to connect to customers behind routers while they configure as little as possible (as they might screw something up).  Any ideas?

what you need to do is forward the ports mentioned in the above instructions for realvnc to the ip address of the server your running it on

http://67.184.75.227:5800 <---For java through a web browser, and http://67.184.75.227:5900 through a VNC viewer.  Open ports 5800-5900 TCP and UDP and you should be fine.

A few things to be sure it works each time,...
First, make sure the PC you are tryiing to connect to is statically set to the 1.10, then in the router have VNC, Ultra or Win or Tight services forwarded to that address using both UDP and TCP on ports 5800 to 5900. Make sure you have holes punched in the firewall for WinVNC at this address range. If you use realVNC, ultraVNC is better and has file transfer features. This above is worded for a Linksys Router, other brands use slightly different terminology. Test it with the firewall off then tweak it with it turned on.

So on the router, if I use say Real VNC (im assuming that you can set the port number on the server software), and I have the ports 5800 and 5900 open on the router, and those forwards are attached to a static address, what is the address I put into the Real VNC viewer?  Or should I just do it through the web browser?  Whats the difference between the two?

You put in what is your true external public IP address which is like eg. 66.230.175.44. Go to the site Whatismyip.com and that should give you that address. You router has that address, it will tell you what it is too in it's setup or status screen.  While your stations are protected as non-public intranet addresses connected to it, those are the 192.168 types or 10.0.0.1, etc. With the forwarding on, the VNC viewer pipes requests through port 5800 or 5900 (or you can change that in RealVNC, not necessary) to the static address you set it to. It is passworded so only you can get in. You have full access with RealVNC where as if you set up just a browser you are more limited and my directions are different.

Yeah I got it working...it turns out that with a router you have to set a static ip on your host and then forward the ports...
