Cisco 827 Transparent Mode?

[DomiNosroB]

Hi all,
I have a Cisco 827 sdsl router. I want to put it into transparent mode so that it passes all traffic to the Eth0 interface. I am not sure if I need to setup a bridge group or what. Please help.

Here's a portion of my current config:

interface ATM0
no ip address
ip directed-broadcast
ip nat outside
ip virtual-reassembly
atm ilmi-keepalive
dsl operating-mode auto
hold-queue 224 in
pvc 0/100
encapsulation aal5mux ppp dialer
dialer pool-member 1
!
!
interface Dialer0
ip address 198.x.x.x 255.255.255.248
ip nat outside
ip virtual-reassembly
encapsulation ppp
dialer pool 1
dialer-group 2
ppp chap hostname xxxxxxxx
ppp chap password 7 xxxxxxxxxxxxxxxx
!

Thanks,

Robert
