NAT loopback - Draytek/Thompson

Hi,

One of our clients had a combination of routers to support al their
needs.
First there is a Thompson Speedtouch 510 ADSL modem which forwards all
requests to the other router on the LAN port.
We installed the other router (Draytek Vigor 2900) because of it's VPN
capabilities.
The Draytek forwards some ports, like 80 for webmail, to the server.

The problem is as follows.

There are several users which refuse to work with outlook/exchange.
Don't ask me why...
So we decided to install outlook and download mail from the pop boxes
on the exchange server. (which they are used to before the server
upgrade)
But now we want them to be able to connect from both the office and the
internet without using VPN!

Now I know there are routers out there which support NAT loopback (like
zyxels).

What I need is the WAN ip to be accessible from the LAN.

Can anyone help me out how to configure the Speedtouch or the Draytek
for NAT loopback?

Thanks,

Leon

Hi Jason,

Don't exactly know if its a 510i or just a 510....but the only
difference between them is the line port (pots or isdn).
The firmware is the latest from the speedtouch website.
And at last, yes the users sucks

Geez, your users suck. That's one of those situations where you wish
you were in house IT, and you just make the change, and tell them to
deal with it. Your Speetouch 510. Do you know if it is a 510i, or just
a 510. What Firmware version are you running on it?
