First, you have to get a Public IP to ISP, with it’s gateway, netmask, broadcast and the DNS. Then you have to provide at least two ethernet card. One to the network, and one to the internet.

sudo gedit /etc/network/interfaces

Then insert this code:

#Ethernet that is connected to the ISP
auto eth0
iface eth0 inet static
address [ public ip for ubuntu pc]
gateway [ public ip from ISP]
netmask [netmask from ISP]
dns-nameserver [dns ip dari ISP]

#For the networks
auto eth1
iface eth1 inet static
address [ private ip for ubuntu pc]
gateway [public ip eth0]
netmask [netmask ip LAN]

Now, activate the IP forwarding by editing sysctl.conf file using this command:

# gedit /etc/sysctl.conf

Erase the (#) sign so the content of sysctl.conf will looks like picture above

Stops the ip tables by executing:

#/etc/init.d/iptables stop

Execute this commands:

#iptables -t nat -A POSTROUTING -o eth0 -s [ip network private/24=eth1] -j SNAT –to-source [ip public=eth0]
#iptables-save /etc/sysconfig/iptables
#/etc/init.d/iptables restart

FTP server can be used to handle FTP services, so the client can store file and also download a file from the FTP server. In Linux, it’s easy and free to build an FTP server. Here’s the guide:

First, install PROFTPD by executing

# apt-get install proftpd

During installation, you’ll be asked whether you want to run proftpd from inetd or standalone. If the traffic is abundant, choose Standalone.

After installed, you now, have to configure by opening proftpd.conf file.

# gedit /etc/proftpd/proftpd.conf

Give a code like below, it will set as a read only directory…

<Anonymous ~ftp>
User ftp
Group nogroup
UserAlias anonymous ftp
DirFakeUser on ftp
DirFakeGroup on ftp
RequireValidShell off
MaxClients 10
DisplayLogin welcome.msg
DisplayFirstChdir .message
<Directory *>
<Limit WRITE>
DenyAll
</Limit>
</Directory>
</Anonymous>

Restart the FTPD, you can use this command:

# /etc/init.d/proftpd restart

For Read/Write, you can use this script:

<Anonymous ~ftp>
User ftp
Group nogroup
UserAlias anonymous ftp
DirFakeUser on ftp
DirFakeGroup on ftp
RequireValidShell off
MaxClients 10
DisplayLogin welcome.msg
DisplayFirstChdir .message
</Anonymous>

Now, you’ll be able to connect to your FTP Server using ftp client softwares, eg: filezilla.

I am currently using Samsung Z170, this gadget is automatically detected in Linux (i use slackware for this testing) as tttACM0. Then, open /etc/wvdial.conf, just enter the connection infromation, eg:

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,”IP”,”insert_APN_name”
Modem = /dev/ttyACM0
Phone = *insert your dial phone#
Idle Seconds = 300
Modem Type = USB Modem
Stupid Mode = 1
Compuserve = 0
Baud = 460800
Auto DNS = 1
Dial Command = ATDT
Ask Password = 0
ISDN = 0
Password = ”
Username = ”

To let wvdial don’t ask password each time you dial, the password and username should be two ‘ (single quotation) character.
