Is there a way you can configure the pix to

ping the outside interface? Not that you would

want to do it..

Thanks

Do you mean to open ICMP port so that you can ping through Firewall?

Not ping through the firewall, but ping the outside

interface of the firewall.

Thanks

When you ping the outside interface of the firewall, what error message do you get?

icmp permit outside sou_net sou_subnet type_icmp

but is permitted by default ?!?!?

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.

Hope this helps,

Neil.
