control and monitor a vi inside a LAN

[Soroush]

Hi,

In LV6.1, I have built an application (.exe) and want to monitor and control it through an HTML page.

There is not any problem when I connect my computer with labview server to internet directly. but in the practical case the labview server is on one the interior machines of a LAN network which connects to internet by its gateway.
So I have defined all the port forwarding rules for the LAN.

I think the problem is about the HTML code itself.
Because when i want to connect to my application from outside, the web browser finds the page, shows its title and texts, but while the panel is downloading i face with this error:

Error: Could not find LVFPPVINAME parameter in the OBJECT/EMBED tag.

I'm sure that the problem i
s not related to the network. It is something about HTML page code itself.
but I don't have any knowledge on HTML.

Can anyone help me?Thnak you in advance.

Soroush,

Take a look at this knowledge base that refers to error that you are seeing: http://digital.ni.com/public.nsf/websearch/40F97DF04378BFAD86256B9E00720B7B?OpenDocument
Could this be what you're running into? If not, post again and we will go from there. Hope this helps.

Thank you for your help Adam.

But it was not the case.

My top level VI names in application, are simple names with no punctuation marks.
The point is, I face this problem only when the labview webserver is behind a NAT in a LAN.
If the server runs on the gateway, I don't see this error message.

Another point: I have TWO top level VIs in my application. will this cause the problem? Two top level VIs in one application. it seems to be permittable. isn't it?

Actually i'm in urgent need of help!
Thank you very much.

Soroush.
