Hello Ralph, Making the exceptions is indeed some work but once configured it's there to stay. We don't use nrpe for windows we use nsclient / check_nt. We have in our monitoring packages different levels of what to monitor , and in case of the customers which have port forwards , they only have monitoring for their servers , not any other devices. So the port forwards are working for this. For customers who have a higher level of monitoring (fe servers + network) we setup vpn tunnels to their network , and the checks are performed via the vpn. As far as I know it's not easy to change the snmp port on some devices , but port forwarding can help you getting this configured for more devices, if the check can use a different port. Peter

E.g when monitoring a second server, you have to redirect nrpe requests via different port, i.e. setup port forwarding for nrpe on different port for the second server But what if you want to monitor via various snmp queries? Do I have to add a duplicate item for every snmp monitor and change the port or can I change the port globally? Thanks and regards, Ralph Arnhem, The Netherlands On Mon, 10 May 2010 11:49 , Peter Plate <[email protected]> wrote: Hello Ralph, This is how we do this : Less then 5 servers = open port forwards to additional servers , configure nsclient on different ports , and make exceptions in the service checks to change the ports. More then 5 servers = create vpn tunnel and check via the tunnel More then 10 servers = Install Slave server on virtual PC / Virtual server at client location , port forward ssh to this slave server. Just our ideas of the setup.

For one server I use port redirection on the firewall/router, but additional servers is difficult since I have only one public ip. What is the best way to monitor these servers?
