VPN Clients behind ADSL NAT

We have a MS Windows 2000 VPN server inside our network
behind a Cisco515e Firewall. The same has been setup to
allow traffic on GRE and TCP Port 1723 and is working fine
for the remote users who are on a dial up network.

But when any user tries to connect to the VPN Server from
our another office only one of them is allowed. The users
in this office are using an ADSL line configured with NAT
to access internet. We are using one Cisco 677 ADSL Router
there. Only one user can connect at a time.

The server does not have a problem connecting multiple
people at a time, as long as they are not coming from the
same network (IE, behind the same router and connecting
using the same IP address).

Is there any way to let multiple people from the SAME
remote network connect to our VPN server?

I have manually configured one NAT entry on the Cisco ADSL
router like this

set nat entry add 192.168.1.0 1024-65535 * 1024-65535 tcp

But this is also of no use.

Any Help in this regard would be highly appreciated.

Thanks in advance.

This would be a question for Cisco. It is probably the "root" of your
problem. It probably just simply doesn't allow more than one VPN connection
from the same IP#. Cisco has always been heavily "proprietary", you should
direct questions about configuring their devices to ether them or to a news
group devoted to cisco equipment.

NAT and VPN are not related. NAT would be a non-issue with this as far as I
can tell.
 
Thanks Phillip,

Yes I know this is the ADSL router problem as it is not a
VPN Multisession passthrough router.

Anyways, thanks for your reply.
