You’ll have to look at the PIX logs to see if the packet is arriving at the outside interface of the pix. The easiest way to do this is to turn on debug icmp and ping the static IP address from the remote site. If you see icmp packets on the debug, dig further into the debugging syslog files to see what is being denied. I assume you’ve setup a conduit allowing these packets in. If the source IP address on the remote site is the same network as the inside network, your host inside will assume the packet came from one of the hosts on it’s own wire and will never use the gateway (PIX) to return the packet to the remote site. Consider using rfc1918 reserved network addresses internally.
