Need advice on router throughput test

I have built a router with FC2 on a PIII. It has 3 interfaces:
Internet, LAN, and DMZ. I'm trying to run sguil (see earlier post

It has been suggested to me that trying to make my router do all this
will effect my Internet connection. I have VoIP and the quality is not
always good. I also have a Linksys router I can use to compare. I
would like to do some real, extended, tests with both routers to
compare the results. I want to test not only TCP but UDP. I want to
do long-term test (not just loading one web page) to see if there are
intermittent problems.

Can anyone give me some advice on how to do a good quality test to
compare these routers?

Thanks!

How fast is your internet connection? If your network is 100baseT I doubt
if your router configuration would even be an issue (or even 10baseT
unless you have a fast internet connection). I only have 1500/384 adsl,
but there is no difference between broadband speed tests run directly on
the Linux router (which has 3 nics), or from a PC routed through a laptop
wirelessly to an AP connected to old 10baseT nic on the Celeron 300 Linux
router.

Not sure where any broadband speed tests are around Israel. But if you
are having ISP or internet routing problems, there may be nothing you can
do unless there is an MTU mismatch somewhere (for example PPPoE has max
MTU 1492 due to its 8-byte header).
