    I have a soho-77 that I am using to replace the Speed Stream ADSL
    Modem from the ISP.

    I have a working config for DHCP and NAT but want to loose the NAT
    part and allow the clients on e0 to receive the Public IP addresses
    assigned from the ISP's DHCP server. This is so I can place my PIX
    Firewall behind the 77



    Current configuration:
    version 12.2
    no service pad
    service timestamps debug uptime
    service timestamps log uptime
    service password-encryption
    hostname Router
    no logging buffered
    ip subnet-zero
    ip name-server
    ip name-server
    ip dhcp excluded-address
    ip dhcp pool CLIENT
    import all
    lease 0 2
    bridge irb
    interface Ethernet0
    ip address 255.255
    ip nat inside
    interface ATM0
    no ip address
    no atm ilmi-keepalive
    pvc 0/35
    encapsulation aal5snap
    dsl operating-mode auto
    bridge-group 1
    hold-queue 224 in
    interface BVI1
    ip address dhcp client-id Ethernet0
    ip nat outside
    ip nat inside source list 102 interface BVI1 overload
    ip classless
    ip route BVI1
    ip http server
    access-list 23 permit

    line vty 0 4
    access-class 23 in
    exec-timeout 120 0
