Titolo: Routing and bridging on cisco routers

Given the following configuration:
    Eth0         Ser0                                       Eth
LAN1----Cisco4000----FR switch-----ATM switch---MUX ADSL--NT-----PC
                        |
                   Ser0 |
                        |
                    Cisco2500
                        |
                   Eth0 |
                        |
                       LAN2
- LAN1 is connected to Cisco 4000 by Ethernet interface and to a Frame Relay
network by serial interface
- LAN2 is connected to Cisco 2500 by Ethernet interface and to a Frame Relay
network by serial interface
- PC is connected to an ADSL Network Termination NT by Ethernet interface
While connecting LAN1 and LAN2 is an easy case of IP routing over Frame
Relay, problems arise when you try to give Ethernet access over ADSL from PC
to LAN1 and LAN2. As on the ADSL side the NT has NO routing capability, the
only way to access LAN1 and LAN2 from PC seems to be a bridging mode on both
Cisco routers.
But can I have BOTH IP routing over Frame Relay between LAN1 and LAN2 AND IP
bridging over Frame Relay between PC and LAN1 or PC and LAN2??
Can Cisco routers do both IP bridging and IP routing on the same interface?
Thanks in advance for any kind of help.
