check_dhcp not working

[Toto Capuccino]

When i write a remote server i mean a server that is not the nagios server.
When i say that it is on the same subnet i made certainly a mistake as
actually the nagios server get an address 10.1.1.13 and the dhcp server i am
trying to ping is 10.2.1.1. I think that the packets are sent through a
cisco switch/router that routes the packets from net 10.1.0.0 to 10.2.0.0 so
that must be the reason of my problem. If dhcp works with broadcasting
messages, the switch is not relaying those dhcp packets. I am right ? Is
there's a way to bypass that ?
