How to Connect your Home Network to xDSL Line

You have your Home DSL modem installed, and want to have a secure connection to the Internet for your home network. For that, you have to install MikroTik router between the DSL modem and your home network:

Follow the steps below to connect your home network to xDSL line:

• Make your MikroTik router with two Ethernet NICs, one for the Home DSL modem, one for your home network. See instructions in the Basic Setup Guide!
• When installing, make sure you install the dhcp software package, if your xDSL service provider uses DHCP to hand out IP configuration.
• Make sure both interfaces are enabled, for example:

/interface enable ether1,ether2

• Add DHCP client on the external (xDSL) interface to receive IP configuration form your service provider:

/ip dhcp-client add interface=ether1 disabled=no

• Check, if you have received IP configuration using print detail, for example:

[admin@MikroTik] ip dhcp-client> print detail     
Flags: X - disabled, I - invalid 
 0   interface=eth1-adsl add-default-route=yes use-peer-dns=yes 
     use-peer-ntp=yes status=bound address=81.198.55.240/22 
     gateway=81.198.52.1 dhcp-server=81.198.232.1 primary-dns=80.232.169.11 
     secondary-dns=195.122.1.59 expires-after=5h5m46s 

• Add your private network address to ether2 interface, for example:

/ip address add address=192.168.0.1/24 interface=ether2

• Configure masquerading for your local network:

/ip firewall nat add chain=srcnat src-address=192.168.0.0/24 action=masquerade

• Configure firewall to protect your router:

• (Optional) Run DHCP Setup to configure DHCP server to hand out IP configuration on your home network:

/ip dhcp-server setup
