Hi,

I'm responsible for several m0n0walls installed at remote locations. I 
have set each of them up to use SNMP and to send syslog messages to a 
machine at my main site.

At the main site, I use ifgraph/rrdtool to produce bandwidth graphs for 
all of the other m0n0 boxes. This provides a very easy-to-use method of 
connection monitoring - you can see how long the link went down for and 
when.

This is all done via IPSec VPN between the m0n0walls - so all the 
SNMP/log traffic is encrypted. If the link is dropped, m0n0 will try to 
reestablish it.

Works quite nicely IMO, I'm looking for ways to improve it though :)
