Hey Guys,

I'm a newbie and am probably asking a question that has been asked too often.

Here goes:
I'm using Comcast as my cable provider and I can't connect to my company's VPN (I work remote). I'm connecting my cable modem to a D-Link DI 604 4 port router. When I connect direct from my cable modem to my laptop, I can connect with no problem. But, when I connect my cable modem back into my D-Link router I can not log onto my VPN.

What I've done so far:
I called Comcast and then said I need a static IP and goto DynDys.org and register - but I really don't know if they're right. And, if they are, they couldn't tell me which service I would need.

I need help - anyone out there who knows how to direct me so I can solve this problem?

Any and all recommendations are most welcome.

Thanks,
Gunnar

You would need to purchase a VPN router. D-Link makes one.

You could try using the "DMZ Host" and port forwarding features on the router, but I don't know if they would work.

Frankly, you should just unplug the router and bypass it.

Hard to imagine their support actually said that but if so that is unbelievably stupid. Your IP does not need to be static. If it were static then there would be no reason to use a dynamic dns service. They're idiots if they said that to you. Whether or not YOUR IP is static is completely irrelevant in this action. It just needs to be a valid WAN/Public IP, which is what your router will have. Your PC will have the internal address.

You don't need a "VPN" router. You do need one that at least has VPN passthrough. Your not running the VPN server if I read your post correctly. All you have on the client side is the VPN client software. Cisco, Nortel Contivity, whatever. Your router needs to support VPN passthrough. Pretty much any decent contemporary NAT router will do this but you can look at your manual to make sure. Putting it in the DMZ isn't a bad idea if it just won't work. Shouldn't have to unless your router is older and doesn't support passthrough.
