Hi No, I am not trying to bridge accross a WAN link. We just need the 2 routers (the 1801 and the router being supplied by an external company) to each have one of our 2 external IP addresses. The 1801 will be connected to the ADSL line, and the other router will be connected to an ethernet interface of the 1801. The 1801 would also be the default gateway on our network, performing NAT and port forwarding. Mark

Is it possible to configure a router in the following way, if so can somebody please point me in the right direction? At one of our sites we have an 1801 which is connected to the internet using the DSL interface, and to the internal network using the switch ports. We have another company who are installing a second router for a static VPN, and they want it to have an external IP address assigned to it. We are on a /31 subnet, so only have 2 useable IP addresses, but currently only use one of the IP addresses. We would like bridge the DSL interface and the (currently unused) interface FastEthernet 0, so that the other company can connect their router to FastEthernet 0 using the second external IP. I have tried doing so, but as the DSL connection is using PPP it goes down as soon as it is added to a bridge group. This is the current ATM / dialler configuration we are using: interface ATM0 no ip address no atm ilmi-keepalive dsl operating-mode auto interface ATM0.1 point-to-point pvc 0/38 encapsulation aal5mux ppp dialer dialer pool-member 1 interface Dialer0 ip address xxx.xxx.xxx.xxx 255.255.255.248 ip nat outside ip virtual-reassembly encapsulation ppp dialer pool 1 dialer-group 1 ppp authentication chap pap callin ppp chap hostname username ppp chap password 0 password ppp pap sent-username username password 0 password Any advice would be greatly appreciated.
