im looking at the config of a cisco 871 the bridge interface looks to my lan interface. 

how do i check which physical ports are part of the virtual bridge interface  ? 

#sh ip int br
Interface IP-Address OK? Method Status Protocol
BVI1 10.1.6.1 YES NVRAM up up
FastEthernet0 unassigned YES unset up up
FastEthernet1 unassigned YES unset up down
FastEthernet2 unassigned YES unset down down
FastEthernet3 unassigned YES unset up up
FastEthernet4 205.202.22.195 YES DHCP up up
Tunnel6 10.10.6.1 YES NVRAM up up
Tunnel11 192.168.3.2 YES NVRAM up up
Tunnel12 192.168.2.2 YES NVRAM up up
Tunnel13 192.168.8.1 YES NVRAM up up

Hello,

not sure if there is a command that shows you all bridge group members, but you could use something like the below:

871#sh run | i Fast|bridge-group 1

The output would at least show you which FastEthernet interfaces are in bridge group 1....

#sh run | i Fast|bridge-group 1
tunnel source FastEthernet4
tunnel source FastEthernet4
tunnel source FastEthernet4
tunnel source FastEthernet4
tunnel source FastEthernet4
interface FastEthernet0
interface FastEthernet1
interface FastEthernet2
interface FastEthernet3
interface FastEthernet4
ip address dhcp client-id FastEthernet4
bridge-group 1
ip route 0.0.0.0 0.0.0.0 FastEthernet4
ip nat inside source list 1 interface FastEthernet4 overload

and correct model # is C870
