Query: Doesn't work with Nortel VPN

I have a wired D-Link router that works great with my company's Nortel VPN. So, I bought this wireless router for my laptop. After trying for days and days to get it to work I tried different configurations and contacted Tech Support. At first Tech Support offered suggestions to make it work, but didn't ask the right questions.It was only after my company's tech support and I searched Google and D-Link's website did we find that this D-Link router doesn't support Nortel VPN with NAT. D-Link is a great product, but research first if it works with your configuration.
