Configuring a Draytek router and BT Static IP addresses using the WAN IP alias

We have a Draytek Vigor 2820 router and BT Business broadband, with the package comes 5 static IP addresses. We've recently had problems creating a VPN connection to the router and from what I've read I need to configure it to work with the static IPs. I've followed a guide (http://www.draytek.co.uk/support/kb_vigor_multinat.html) to adding the static IPs as a WAN IP Alias (i've not configured any ports) and I still seem to be having issues connecting.

Other than adding the IPs as WAN Alias's what else do I need to do?

Could you possibly describe the ''issues'' further?

e.g. error messages, error codes, any other info you can collect.

The machine trying to establish a VPN link isn't able to connect or resolve the IP address at all, even when a trace is set.

Thanks for your help. We're looking to establish a VPN directly to the Vigor.

Our ISP have assigned us 5 static IP addresses, I've entered them in as WAN IP Alias's which has had no affect. I did manually enter the static IP address once the router had restarted we could not access the internnet.
Could you find something in the obove link? or do you guiding help to understand those things?

If you want you could put more information about the other vpn partner GW, so I could help you work out the VPN you need to have.

The best is if you could make simple drawing about that:

[LAN1: x.x.x.n mask: /m1 ]
GW1: x.x.x.p1

type of VPN: IPSEC?
Method: AH or ESP

LAN2: y.y.y.n mask: /m2
GW2: y.y.y.p2
Is the vigor directly connected to the internet or is there a BT router/modem in between.. if there is thats what needs reconfigured.
The router connects directly to the Internet as it has a built in ADSL modem.
"The machine trying to establish a VPN link isn't able to connect or resolve the IP address at all, even when a trace is set."
It is not really clear what you want to achieve.
Are you going to use your draytek as VPN Gateway? For Client to Site or Site to Site VPN.
Or do you need to know how to configure the Draytek for VPN passthrough?
Or do you need to know how to configure the Draytek to allow inside VPN GW?
