You may want to checkout SmokePing which works off of RRDTool. It sends 10 pings ever 2 minutes, averages and graphs their response time and loss if any.
Sounds like a nice tool, thanks for the pointer. But....
You would setup a host internally with smoke pings against the inside interface of the PIX, and the router just outside the PIX, then compare the graphs.
As the latency across the firewall hopefully isn't great, would not the potential difference between the ping-response time of the firewall and router be significant? Surely such a test would be better constructed with two identical, unloaded hosts - one just inside the FW and one just outside? Ob FW: Whilst obviously anything that's not simply routed (e.g. proxied protocols) would be a completely different kettle of fish, to what extent could one then reasonably generalise the results obtained from ping tests (i.e. ICMP packets) to other protocols?
