E4200v2 - DHCP client list NEVER displays

Question

As the most expensive and hyped "consumer router" at the local big-box stores, and after already returning a Netgear N600 that appeared to be defective, I had high hopes that this router would work properly and I could stop fooling with router settings and move on to real work. And I'll acknowledge that for a lot of folks this router will probably be fine. I didn't do any speed measurements or methodical testing, but it seems pretty fast and using it for more than three weeks it seemed reliable. However, it had several issues that were maddening and ultimately for me, unacceptable. Summarized as follows:
> The DHCP client list NEVER displays all the clients connected on my network, no matter how many times I look. These clients are actively transferring data, and I can download free programs from the web that report all clients reliably. Why is this so difficult??
> The logging feature is ridiculous - it often didn't log events that I knew had occurred, and even when they were shown, you would only see an entry if you checked the log very quickly after the event (some sort of "auto-flush" function that makes the whole feature pretty useless).
> The previous issues are annoying - but this was the deal-breaker. I could not connect to an OpenVPN device on my network through this router. I could connect to the device locally, I could connect to other devices remotely through other forwarded ports, and I could see in the log (if I looked quickly enough) that the router was seeing the connection attempt to the OpenVPN device, but it was getting blocked. Many hours searching forums and experimenting with router settings / firmware updates did not help.
> In the pursuit of resolving the third issue, and with very low expectations, I contacted Linksys tech support. This proved to be a complete waste of time. After working through the front-line guy who only knew how to look through the User's Guide, I was connected to another person who was even more clueless and was almost robotic in his hard-coded sequence of attempts to guide me through silly procedures that had absolutely nothing to do with my problem. After again asking if I could speak to someone that might actually understand the issue I was put on hold for more than 20 minutes, at which point the call was disconnected (I think this means they hung up on me).
So once again I'm returning an expensive router that doesn't work properly and will be trying something else. It shouldn't be this difficult.

With reference to your post I would like to know that does all the client devices on your network runs on DHCP or some of them have static IP address as well? The devices which are running on static IP address will not be displayed in the DHCP client table.
Regarding the logs that are not being created on the router for any event that takes place could be because of the reason that you might be using another router or a gateway before your linksys router.
As far as your VPN issue is concerned please try to disable the firewall of the router and then try to connect to the open VPN device because this router acts like a VPN passthrough.
