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:

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.
Enable both interfaces, for example:
```
/interface enable ether1,ether2
```
Configure DHCP client on the external (xDSL) interface to receive IP configuration form your service provider:
```
/ip dhcp-client set enabled=yes interface=ether1
```

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

[admin@MikroTik] ip dhcp-client> lease print
          address: 81.198.16.4/21
          expires: may/10/2001 04:41:49
          gateway: 81.198.16.1
      primary-dns: 195.13.160.52
    secondary-dns: 195.122.1.59
[admin@MikroTik] ip dhcp-client>

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 src-nat add out-interface=ether1 
                                      action=masquerade
    comment="Masquerades everything leaving  
                                the external interface"

Configure firewall to protect your router:

/ip firewall rule input add connection-state=invalid action=drop
	comment="Drop invalid connection packets"
/ip firewall rule input add connection-state=established
	comment="Allow established connections"
/ip firewall rule input add connection-state=related
	comment="Allow related connections"
/ip firewall rule input add protocol=udp comment="Allow UDP"
/ip firewall rule input add protocol=icmp comment="Allow ICMP Ping"
/ip firewall rule input add src-address=192.168.0.0/24
	comment="From my home network"
/ip firewall rule input add action=drop log=yes
	comment="Log and drop everything else"

(Optional) Configure DHCP server to hand out IP configuration on your home network:

/ip pool add name=private ranges=192.168.0.2-192.168.0.254
/ip dhcp-server network add gateway=192.168.0.1 address=192.168.0.0/24
    dns-server=195.13.160.52,195.122.1.59 domain="mail.com"
/ip dhcp-server add name=home interface=ether2 lease-time=3h
    address-pool=private
/ip dhcp-server enable home

That's it! You can access the Internet from your home network!
