do you have 2 computers?
if so - simply setup one to talk to the other and do an iperf test
between
Push large amounts of data - and see what happens.
See what happens when you have multiple ports blocked but hitting it -
iperf works well for this kinda thing

imac and a PC laptop generate a lot of 137 traffic that gets blocked.

i. I use the Internet mainly via a D-Link N wifi router connected
to a HP Procurve switch. The firewall is also connected to that
switch.
During heavy (2 people streaming) the network(Internet) keeps
cutting out. For the longest time, I thought it was either the
Verizon DSL service or my in-house phone wiring. Although the wiring
is crappy, I have pared it down to either the HP Procurve 24 port
switch or the pfsense firewall.
I called Verizon last night and plugged a laptop directly into the
modem bypassing the switch and the firewall while the service was
going through on-again, off-again cycles. And voila, the speed
picked right up and stayed up and stable during some big-file
download tests.
So, the question is how do I test the firewall?
