Ikuti langkah-langkah seperti terlihat pada gambar, pada step ke 3, paste command berikut:

delete from radacct  where AcctStopTime='0000-00-00 00:00:00';

Klik Execute (langkah 4)

Selesai

Keadaan topologi network yang saya maksud adalah seperti pada gambar di bawah ini.

Pada Mikrotik:

ether1 (ke modem) = 192.168.1.11/24
ether2 (ke Billing) = 192.168.3.2/24
ether3 (ke Client) = sesuai setting hotspot setup

Pada Ubuntu:

eth0 (ke ether2 mikrotik) = 192.168.3.1/24

Pada mikrotik, setelah hotspot setup selesai, masuk ke Winbox (continue reading…)

Asumsi bahwa koneksi menggunakan Speedy dan mendapatkan ip publik.

ether1 = 192.168.1.11 (mengarah ke modem)

ether2 = 192.168.3.2 (mengarah ke webserver)

ip webserver = 192.168.3.1

DMZ Host pada modem di arahkan ke ip ether1 mikrotik=192.168.1.11

Membuka akses webserver (port 80) melalui webbrowser dari ip publik (luar, port 80)

/ip firewall

nat add chain=dstnat action=dst-nat to-address=192.168.3.1 to-ports=80 dst-address=192.168.1.11 protocol=tcp dst-port=80

Membuka akses ssh (port 22) menuju webserver

nat add chain=dstnat action=dst-nat to-address=192.168.3.1 to-ports=22 dst-address=192.168.1.11 protocol=tcp dst-port=22

Membuka akses ftp (port 21) menuju webserver

nat add chain=dstnat action=dst-nat to-address=192.168.3.1 to-ports=21 dst-address=192.168.1.11 protocol=tcp dst-port=21

Mengakses Mikrotik Webbox (port 80), akan dialihkan ke port 82 ether1

Sehingga nantinya: http://ip_publik:82 akan otomatis diarahkan ke http://ip_mikrotik:80

nat add chain=dstnat action=dst-nat to-address=192.168.1.11 to-ports=80 dst-address=192.168.1.11 protocol=tcp dst-port=82

Membuka akses ftp ke Mikrotik (port 21) dari luar (publik) menggunakan port 23

nat add chain=dstnat action=dst-nat to-address=192.168.1.11 to-ports=21 dst-address=192.168.1.11 protocol=tcp dst-port=23

Yang penting modem udah DMZ ke ip ether1 mikrotik, masalah beres.

Download dulu firefox 3.5.3.tar.bz2 dari situs mozilla, for linux tentunya. Save di /home/userAnda/

Masuk terminal ketik:

sudo rm /usr/bin/firefox && sudo dpkg-divert –rename –remove /usr/bin/firefox && sudo rm -r /opt/firefox

Kemudian lanjutkan dengan ketik:

if [[ ! -f /usr/bin/firefox ]]; then sudo apt-get update && sudo apt-get install firefox; fi && if [[ -e ~/.mozilla ]]; then cp -R ~/.mozilla ~/.mozilla.backup; fi && sudo tar -jxvf firefox-3*.tar.bz2 -C /opt && rm firefox-3*.tar.bz2 && sudo mv /opt/firefox/plugins /opt/firefox/plugins.backup && sudo ln -s /usr/lib/xulrunner-addons/plugins /opt/firefox/plugins && sudo dpkg-divert –divert /usr/bin/firefox.ubuntu –rename /usr/bin/firefox && sudo ln -s /opt/firefox/firefox /usr/bin/firefox

Diketahui:

eth1_mod = ke modem

eth2_lan = ke klien/hub

maka,

ip firewall nat add action=masquerade chain=srcnat
ip firewall filter add chain=input connection-state=invalid action=drop
ip firewall filter add chain=input protocol=udp action=accept
ip firewall filter add chain=input protocol=icmp action=accept
ip firewall filter add chain=input in-interface=eth2_lan action=accept
ip firewall filter add chain=input in-interface=eth1_mod action=accept
