There is no VPN involved as our network is only private circuits. As for 
a route, that would not explain why I could telnet to the device, but 
not ping. The problem is very specific to ICMP. As well, having another 
machine on the same switch being able to ping the device indicates it is 
not related to the network, but more specifically to the Nagios server. 
I'm only running a default gateway with no routing protocols and no 
static routes. I've checked the routes on the device before and after 
the problem and the do not change. It is a very wierd problem.
