howto build an environment with 2 firewalls?

[WN]

Hallo,

I want to use this configuration:

VNCViewer -> Firewall1 -> VNC Repeater -> Firewall2 -> WAN -> Firewall3 -> NAT-Router -> VNCServer

Connection until the firewall3 works, but I can't connect to the VNCServer (behind a NAT with 10.x.x.x adress...
So what do I have to configure behind the third firewall (customer firewall)? There are 150 systems and its not possible do open the firewall for 150 systems. So whats to do? Install a proxy? Do I need a special VNC-Proxy and where can I get it? Where can I find a good instruction for for this configuration.

Many thanks!

Hello redge,

thank you for your answer. Our problem is a little bit complex (e.g. we want to binding uvnc into our webportal,...). Thats why we try another way.

Thanks
