i m a newbie in RedHat Linux. i've practiced the tutorials of this site about MRTG. but it worked only with public ip. how can i make it use with private ip ?? let me explain details abt what i m going to do:

i've a RedHat 8 Linux machine using as router for my 3 client machine. I got a private ip frm my isp.

eth0 : 192.168.100.99 (connected with ISP)
eth1: 192.168.1.1 (connected with lan)

now i want to use another linux machine for MRTG server with

192.168.100.100 on eth0
192.168.1.x on eth1.

please let me know what will be my /etc/snmp/snmpd.conf configuration.

and what will be my cfgmaker command
