D. Membangun Router 1 (OS Redhat)
1. Masuk sebagai root
2. Check ip dengan perintah
#vi /etc/sysconfig/network-scripts/ifcfg-eth0
Kurang lebih tampil seperti dibawah ini :
Lakukan setting eth1 yang hampir sama dengan eth0, dengan ip sesuai Ketentuan.
#vi /etc/sysconfig/network-scripts/ifcfg-eth1
3. Edit file resolv.conf
#vi /etc/resolv.conf
4. Restart network
#service network restart
5. Aktifkan IP forward
#echo 1 > /proc/sys/net/ipv4/ip_forward
#vi /etc/sysctl.conf
Edit nilai net.ipv4.ip_forward yang awalnya 0 menjadi 1.
6. Setting firewall iptables
#route add default gw 10.10.10.1
#/sbin/iptables -t nat -A POSTROUTING -s 10.0.0.0/8 -j MASQUERADE
#/sbin/iptables -t nat -A PREROUTING -s 10.0.0.0/8 -p tcp --dport 80 -j REDIRECT --to-port 3128
#service iptables save
#chkconfig iptables on
#ping 202.110.101.1
#ping 10.210.254.2
