The reason you don't see much information is because once the path 
is established, the bytes passed are not reported to snmp (I think).

I'm betting the backplane is where most of the traffic is getting
routed.

As for the number of vpn users, you can easily write an external script 
that collects the information and stores it in an mrtg archive.

Hello listers. I am a new MRTG user and I must say I'm hooked on the 
product. Great stuff. Anyway I have a few questions and I hope that I
can 
provide enough info so that I can get real good insight.

I have started using mrtg on a win32 test box. It has been running for 5

days on the core router 6500 router side, two remote connect routers and
the 
internet firewall. Today I configured the 6500 gigabit switchports to
also 
get snmp info. I have noticed not much traffic above the 640.0 K usage, 
maybe 1.2M. I am using mrtg 2.10.15 and I thought it was a versioning
issue 
but noticed some others in the archive had similar issues though no 
resolution. As an aside the low numbers are showing up on my nokia
firewalls 
and the numbers are kind of inconsistance with the bandwidth stats from
my 
isp.

Thoughts or comments much welcomed!

Upcomming I am trying to figure how I can track amount of vpn users
logging 
into my checkpoint ng ai and amount of vpn traffic.

Thanks all!
