Normally if you have enabled routing on the NAT system and if you can see ICMP req coming to the inner interface then this ICMP req should be routed to the external interface (WAN (PPP/SLIP) Interface if I understand your configuration). If you can’t see this packet anymore then probably the normal behavior is broken. It can be coused by enabled native XP connection sharing, firewall or third party NAT/gateway software. I suspect that this is rather the firewall which just drops ICMP packets but I can’t know it for sure.
