We've tested a product in our LAN. All the web pages and the NB server functions are fine. But one of our customer complain that some of the web page from the NB doesn't show up on their VLAN. If direct hook up to the NB with his laptop, it works fine. He's 500km away from the NB now and is frustrating by not being able to access some of the pages.
It's using NBEclipes 2.5.3. on SB70LC.
Any idea what causes? Operating system or our application?
Thanks in advance,

Are you using JAVA? Are your web pages simply talking throught port 80 alone? Some are showing up but not others? Is your customer using a different browser than you developed on? Is there any sort of filter between the module and the customer? router? NAT?

No, I'm not using Java. Only HTML and some java script. Yes, all web pages are talking through port 80 alone. He's using the same browsers: FF, IE as we do. If there is filter between the module and his laptop, then it should either show or not show at all. But he said some pages show and some don't in his VLAN. When he got the module and connected it directly to his laptop, all the pages showed.

Is this a speed issue?
IE are you trying to reload pages automatically in a way that is too fastt for the slow remote connection?
Is this a system with a NAT router that has a limited number of translation sockets between it and the device?
Do purely simple static HTML pages work ok all the time?
Try loading the page echo.htm
does it load every time if you hit F5 a bunch?
More data needed, clearly something in your remote network system..... is different, speed or filtering or nat translation....
Best way to figure it out is with a capture of the working and non working network trace.
