Cisco 804. Making it dumber

    I'm not a Cisco or networking guru, so forgive me if this is a stupid
    question.

    My internet connection is via ISDN and a Cisco 804 router. I'm
    currently wanting to do some experimenting with using a Linux PC as a
    router/gateway-thingamabob so I need someway to hook ISDN up to this
    PC.

    While I could go with an ISDN serial modem, the connection
    throughput/latency is much worse than via the Cisco router. So what I
    need to do is this:

    ISP <---> Cisco 804 <---> Linux PC <---> LAN

    I'm not quite sure how some of this would work. But I'd like to do as
    much of the routing/firewalling/gatewaying duties on the PC as I can.

    Suggestions?

    That will work. just need 2 nics in your linux pc and do nat routing on
    it as well.

    I have friends who do this.

    Worse case there is NAT on the 804 isdn router. IF thats the case you
    get to deal with double nating 2 fake networks which will let you out
    to the internet fine but don't expect to allow any inbound connections
    easily.

    Is it possible to disable NAT on the 804?

    I guess basically I just need the 804 to get the IP and then bridge
    (not sure if this is the right terminology) it straight to the linux
    PC.
