  3. PC Router PC Router adalah Personal Computer (PC) yang digunakan sebagai Router (routing) biasanya yang digunakan adalah PC Multihomed yaitu Komputer yang memiliki lebih dari 1 NIC ( Network Interface Card).

  4. Kelengkapan peralatan • Kebutuhan yang diperlukan dalam mendesain jaringan • dengan PC Route adalah : • Komputer • Kartu Jaringan (NIC) 2 buah atau lebih • Kabel jaringan • Switch

  5. Kelengkapan Konfigurasi • CD OS Linux Redhat 9 • Komputer ( Ready ) • Kartu Jaringan (NIC) 2 buah atau lebih ( Ready ) • Kabel jaringan ( Ready ) • Switch ( Ready)

  6. Lakukan Instalasi OS Linux Redhat 9

  7. Konfigurasi PC Router

  8. IP Privat ( Internet Service Provider - ISP) IP Address : 202.124.13.100 Netmask : 255.255.255.248 Gateway : 202.124.13.100 DNS : 202.130.200.200 IP lokal ( ip yang diberikan oleh admin) IP Address : 192.168.10.1/24 – 192.168.10.255/24 Netmask : 255.255.255.0

  9. Setting Network # vi /etc/sysconfig/network NETWORKING=yes HOSTNAME=localhost.localdomain GATEWAY=192.168.1.254 lalu simpan dengan menekan :wq

  10. 2. Setting eth0 # vi /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 BOOTPROTO=none ONBOOT=yes IPADDR=192.168.1.200 NETMASK=255.255.255.0 USERCTL=no PEERDNS=no GATEWAY=192.168.1.254 TYPE=Ethernet NETWORK=192.168.1.0 BROADCAST=192.168.1.255 lalu simpan dengan menekan :wq

  11. setting eth1 # vi /etc/sysconfig/network-scripts/ifcfg-eth1 # vi /etc/sysconfig/network-scripts/ifcfg-eth1 DEVICE=eth1 BOOTPROTO=static ONBOOT=yes USERCTL=no PEERDNS=no TYPE=Ethernet IPADDR=192.168.10.1 NETMASK=255.255.255.0 NETWORK=192.168.10.0 BROADCAST=192.168.10.255 lalu simpan dengan menekan : wq

  12. 3. Seting DNS resolv.conf # vi /etc/resolv.conf nameserver 202.130.200.200 search localdomain lalu simpan dengan menekan :wq

  13. 4. Setting ip_forwarding # vi /etc/sysctl.conf net.ipv4.ip_forward = 0 menjadi 1 lalu simpan dengan menekan :wq

  14. 5.Restart Network # /etc/init.d/network restart 6. # chkconfig --level 2345 network on

  15. 7.Lakukan Pengujian # ping 202.130.200.200 # ping google.com 8. # /etc/init.d/named restart 9. #chkconfig --level 2345 named on 10.Restart Network # /etc/init.d/network restart

  16. 11. Matikan iptablesnya # /etc/init.d/iptables stop 12. # /sbin/iptables -t nat -A POSTROUTING -o eth0 -s 192.168.10.0/24 -j SNAT --to-source 192.168.1.200 13. # /sbin/iptables-save > /etc/sysconfig/iptables 14.# /etc/init.d/iptables restart 15. # iptables-save

  17. 16. Seting IP Client1 Ip Address : 192.168.10.2 Netmask : 255.255.255.0 Getway : 192.168.10.1 DNS : 202.130.260.250 17. Seting IP Client2 Ip Address : 192.168.10.3 Netmask : 255.255.255.0 Getway : 192.168.10.1 DNS : 202.130.260.250
