Monitor 2nd mail server behind natted router

[Alex Dehaini]

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) --------

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.

Thanks,
Lex
