    Mark,

    Look into using CAR as Roger Reynolds mentioned to throttle TCP, UDP, ICMP
    or all IP. The downside with CAR is your inability to limit by packet
    count, rather relying on collective packet sizes.

    Look also at TCP Intercept applied to an egress interface (albeit, only
    applicable to TCP). You may also wish to investigate using NAT (possibly
    PAT) with an ACL to limit egress.

    CAR example:

    interface Serial0/0
     rate-limit output access-group 100 8000 1000 2000 conform-action transmit
    exceed-action drop
    ! Where 8000 = rate limit, 1000 = normal burst rate, 2000 = max burst rate
    ! all in bytes
    !
    access-list 100 permit ip any any
    ! Change ACL to match protocol accordingly

    Is anyone from cisco.com on the list that can chime in on this one? I would
    certainly appreciate some PIX configs that would be analagous to the ones
    used for checkpoint firewalls.
