    Are you getting anything on your logs?

    Is the MASK correct on the router?

    Can you ping from the PIX to the router?

    Does the Router IP show up in the PIX ARP table, is the MAC correct?
    Ditto on the router side.

    If all of these fail setup a capture on the PIX inside interface for all IP on that subnet and try again. You might be getting packets it's not expecting (malfromed MACs etc), or none at all...
    access-list CAPTURE-INSIDE permit ip any any
    capture CAPTURE-INSIDE access-list CAPTURE-INSIDE int INSIDE buffer 1000000
    then use 'show capture CAPTURE-INSIDE' to view (or download to your PC for wireshark analysis etc.)
    We responded to the Year 2000 issue with "Y2K" solutions...isn't this the kind of thinking that got us into trouble in the first place?
