They provide ONT(Optical-fibre Network Terminal) for fibre connection without router/firewall/networking features.

Ok, this is what an ONT is:
https://secure.dslreports.com/faq/12565
So you just need a router.

You can get any router that has the features, and I would recommend one that supports open firmware.

Or, if you have two NICs and a switch you could make your computer a router and output to the switch, which can have as many ports as you like, but your computer would have to stay on all the time that you want internet.

Thanks for your advice and link.

I have searched some routers. I'll post them later for advice..

1)
That is my most interest learning how to share Internet connection to a second computer (I have only 2 computers and a spare Gigabit NIC resting on shelves). I know it is impossible. I'll make some search later.

2)
On each PC there are about 10 VMs installed but not all running at the same time. If without a router how can the VM be accessed on Internet (outside). Should I need to buy a switch I prefer to buy a router instead

Thanks

It is possible. If you run Ubuntu, here's a guide:
https://help.ubuntu.com/community/Router

If you only have two computers, you don't need a switch. Just connect one to the ONT and set it up as a router, and connect them together. So you need 3 NICs total. This is what I have done in the past and it works fine, and you save some money in some cases.

Lot of thanks. Otherwise I have to googling around for instruction.

I'll start after making some house keeping copying the important data to the backup HD.

Computer-1 (for daily working)
SSD 120G - OS (Ubuntu 12.04)
HD-1 2TB - for data and VMs
HD-2 1TB - for data backup

Computer-2 (spare)
SSD 120G - OS (Debian 7.3)
HD-1 1.5TB - for data and VMs
HD-2 1TB - for data backup

I'll install Computer-1 as router

Absolutely agreed. Additionally I will learn to setup a PC as router.

I'll come back to report my progress. Thanks

Hi metaschima,

I'm now going through the documentation - Router
https://help.ubuntu.com/community/Router

Re. 4.3.1.3. For Static IP Address Only
Code:
....
auto eth0
iface eth0 inet static
    address xxx.xxx.xxx.xxx
    netmask xxx.xxx.xxx.xxx
    gateway xxx.xxx.xxx.xxx
The static IP address is provided by my ISP, say 2xx.2xx.2xx.1xx. Nameservers (2 nameservers) are also provided by ISP. Where can I get netmask and gateway addresses? Ask ISP?

Thanks

bridge-utils is already running on Computer-1 which runs Oracle VirtualBox as virtualizer.


Edit
====
Port forwarding

If I need to forward port 80/8080 to IP 192.168.0.28 (for example) which is the IP address of a VM on Computer-1 how can I set this request? Domain will point at the static IP so that users can browse the website running on this VM.

You should ask for the rest of the info, or you can use DHCP, which is much easier and more flexible. You may want to setup a DHCP server on your router.

You can forward all ports, not just port 80, unless there is a specific reason.

Can I install the router and DHCP server on a VM instead on the host? I expect keeping the host clean only for running Oracle VirtualBox.

I found some tutorials on setup and configuring DHCP server:

Dynamic Host Configuration Protocol (DHCP)
https://help.ubuntu.com/12.04/serverguide/dhcp.html

How To Set Up A DHCP Server For Your LAN
http://www.howtoforge.com/dhcp_serve...x_debian_sarge

I haven't dealt much with VMs, so I can't be sure if it would work. It depends on the VM and privileges.

In the past I did try to setup static IP based networks, but I have found them to be too inflexible. If I change anything I have to redo configs. Setting up the dhcp server is reasonably simple.

Hi,

Performed following test :
(Documentation referred
Router Guide
Setting up an Ubuntu Wired/Wireless Router
https://help.ubuntu.com/community/Router
)

VM - Ubuntu 12.04

$ cat /etc/network/interfaces
Code:
auto lo
iface lo inet loopback

auto eth1
iface eth1 inet static
    address 2xx.2xx.2xx.1xx
    netmask 255.255.255.0
    gateway 2xx.2xx.2xx.1xx

auto eth2
iface eth2 inet static
    address 192.168.0.1
    network 192.168.0.0
    netmask 255.255.255.0
    broadcast 192.168.0.255

auto br0
iface br0 inet static
    address 192.168.0.1
    network 192.168.0.0
    netmask 255.255.255.0
    broadcast 192.168.0.255
Two NIC detected as eth1 and eth2

Host - Debian 7.3
$ cat /etc/network/interfaces
Code:
auto lo
iface lo inet loopback
Settings -> Network
Adapter 1
Attached to: NAT

Adapter 2
Attached to: Internal Network

Pulled out the cable connecting Cable Modem to Router and connected it to "network card 1". Unable to connect ISP server.

Also tried "network card 2", with same result.

Try some more guides:
http://www.server-servers.com/homese...twork-gateway/
https://rbgeek.wordpress.com/2012/05...ateway-router/
http://www.yourownlinux.com/2013/07/...as-router.html

one of them has to work. Overall, the checklist is:
enable ip forwarding
fix firewall
setup a dhcp server
connect

Thanks for the links.

I suppose my real problem is to make the virtual NIC on VM to connect ISP directly without going through the host.

Hi,

I found following documents which are quite interesting to me:

1)
Notes/Virtual Linux Router with VirtualBox
http://wiki.smalleycreative.com/Note...ith_VirtualBox

2)
Tutorials:Using Linux Virtual Machine instead of router for VPN
http://wiki.hidemyass.com/Tutorials:...router_for_VPN

3)
Creating a Virtual Network of Linux Guests using VirtualBox
http://sandilands.info/sgordon/creat...ing-virtualbox

I haven't gone through all of them deeply. On 3) it seems needing 3 NICs?

Only if you want two internal networks.
