ADSL RFC1483 RBE 7200 2024 private link

Can anyone tell me if this is possible;

I run a 7200 router with an ATM interface that is used for ADSL
subscriber aggregation.
The subscribers run ADSL modems in RFC1483 bridge mode, and each
ADSL/ATM PVC is bridged to a loopback interface on the 7200 with RBE,
as follows;

interface ATM4/0.38 point-to-point
ip unnumbered Loopback0
atm route-bridged ip
pvc 1/38
encapsulation aal5snap

The 7200 is connected to a Catalyst 2924 switch via ethernet. 802.1Q
VLAN trunking is being used between the 7200 and 2924 with multiple
VLANs.

I would like to bridge 1 ADSL subscriber to 1 port on the 2924 in order
to provide a private link between the network connected to the single
port on the 2924 (via another router, 3620) and the network connected
to the remote ADSL modem (another 3620).

The full path looks like this

Subscriber LAN_1 <> 3620 <> ADSL modem in bridge mode <> Carrier ATM
network <> 7200 ATM interface <> 2924 switch <> 3620 <> Subscriber
LAN_2

I have managment access to all network elements with the exception of
the carrier ATM netword (the DSLAM and ATM switch).

The 2 3620s do not have IPSEC IOS images, and there is one application
that does like packets fragmented, so a VPN tunnel is not a good
option.

Is there any way to build a "private link" where the other hosts routed
via the 7200 can not access either of the subscriber LANs, and the
subscriber LANs can not access any networks other than the 2 connected
networks?
