<div dir="ltr">Nagios is on a public IP, the router is on a public IP and the two servers are on local IPs. Here is the connection mail1(localIP) -------- ------------- MailRouter(PublicIP) ----- Switch ------- (Nagios)(PublicIP) mail2 (localIP) -------- <div class="gmail_quote"> If the two servers have the same local IP, there will be IP conflict. NSClient basically sends info from the server to nagios. I can do that for one mail server, I wonder if I can do that for the sendcond one.

Can you easily access or ping the server ? <div class="Ih2E3d"> On Monday 20 October 2008 10:34:06 Alex Dehaini wrote: > Hi Guys, > > Our email server is currently behind a cisco router.
