Burton,

OK, that's one way to go....

Just anonther question: The traffic ntop shows under "other" is this really all other 
traffic? We have a second VPN running on Microsoft RRAS, this traffic appears on 
"other"... Or the other way round: is the sum of what I see on ntop's traffic pages 
really the sum of all traffic on the wire? I'm aware of the hub/switch problem, we 
have ntop running on a hub... Is there anything which isn't counted at all?


Thanks

Not a clue.  The problem, of course, with a VPN is that you either sample INSIDE the 
security perimeter, where upon the VPN is irrelevant, or you sample OUTSIDE, and 
everything is opaque.  You see GB of traffic and no clue what's in it.

How about applying basic diagnostic techniques here?  Hub the output port so you see 
the traffic and (using an unnumbered interface Linux box or some such), use ethereal 
or tcpdump to grab the packets that AREN'T IPSec. Something like (I *think*)

tcpdump -i xxxxx -e -X "! ip proto 50"

or similar...  Should show you what ELSE is going on outside the watchguard.

Otherwise, you should probably contact tech support for the gizmo you bought...

Hi,

Perhaps a little bit off-topic....We have a new VPN running using a Watchguard 
SoHo-Box... We're monitoring our traffic on the router with MRTG and see a permanent 
"noise" on the line after we plugged the box in... But we don't see any significant 
traffic with ntop, just a little bit on IPSEC.... I guess I have to enable other 
protocols, but which and how?


Thanks,
