DHCP與NAT安裝與設定

DHCP

#yum -y install dhcp (安裝dhcp server)

#vi /etc/dhcpd.conf

subnet 192.168.10.0 netmask 255.255.255.0 {

       range 192.168.10.101 192.168.10.200;

       option routers                  192.168.10.254;

       option subnet-mask              255.255.255.0;

       option domain-name              "test.spes.tyc.edu.tw";

       option domain-name-servers      163.30.167.14;

       default-lease-time 21600;

       max-lease-time 43200;

}

NAT

#vi /etc/sysctl.conf

# 將底下這個設定值修改正確即可！ (本來值為 0 ，將它改為 1 即可)
net.ipv4.ip_forward = 1
#iptables -t nat -A POSTROUTING -o eth0 -s 192.168.10.0/24 -j MASQUERADE
