I have been informed by my suppliers that it is a "feature" of the PIX firewall that it will only allow you to ping the interface that you are connected to e.g. inside and no other interface (I come from a router background and assumed you could do this - it took me a while to discover this).
There is no way that I know of that will let you do this. One way round it would be to connect to an external device (e.g. router) and try and ping backwards - as long as you access list allows icmp echo reply on that interface.
