what nagios plugins?
monitoring the networks equipment and server : I have two problems
the first: how to configure a router contains more IP address (path).
the 2nd: how to configure a switch without level 2 IP address

Re: what nagios plugins?
Can you provide a bit more information about what you're trying to do? What OS is your server running?

I doubt there will be a plugin specifically for this, as that's not really how your typical plugin is meant to operate.
Most plugins check something on a schedule, or when needed. They check CPU usage every 5 minutes, disk usage every hour, etc. This type of event, an address connecting to your server, is very hard to monitor for many reasons. First, it's something that is probably happening several times per minute, which means lots of alerts (potentially). Second, it's hard to define exactly what should be displayed for a given service - do you have a separate host for each potential IP that could contact you? Do you have one service for all connections? If you do the first, you're going to have literally millions of hosts to manage, and if you do it the second way the information will update so frequently that it's almost useless.
The better way to do this is at the firewall level, but even then you run into a similar issue where you're likely to be overloaded with information due to the sheer number of connections.

There are plenty of plugins for checking various network metrics:

and even one to check specific connection types:

But I am very doubtful that there is a plugin that will detect every single time someone connects to your machine. As mentioned before, this would best be handled by logging on your firewall.
