My Mikrotik Configuration (part 2)

Previous... My Mikrotik Configuration (part 1)
Step 2, Security.
Setup username and password
user set 0 name=ngeri password=ngeri group=full
user add name=user01 password=password group: read

Don’t use default user admin. Look at what I have done. I change the default user to be other user name. Don't forget to setup the password. It will make your mikrotik more secure.
Firewall in Mikrotik

Setup Firewall.
by grouping IP networks will make it easier to configure the firewall later.
IP-LAN, IP addresses for Lan.
Full-trust, IP Public can be fully trusted. Admin can remotely the Mikrotik.
half-trust, IP public that are not fully trusted, Sometimes, This IP address can be used by admins to remotely the Mikrotik.
Local-untrust, IP address that is not trusted.
/ip firewall address-list
add address=10.17.123.0/24 disabled=no list=IP-LAN
add address=10.254.128.0/22 disabled=no list=IP-LAN

Drop IP address Local unused or untrusted
/ip firewall filter
add action=drop chain=forward comment="Drop Local Untrust" disabled=no \
    src-address-list=local-untrust
add action=drop chain=forward disabled=no dst-address-list=local-untrust

Drop Connection invalid.
add action=drop chain=forward comment="drop invalid connections" \
    connection-state=invalid disabled=no
add action=accept chain=forward connection-state=established disabled=no
add action=accept chain=forward comment="allow related connections" \

For communication Mikrotik with other DNS Server

add action=accept chain=input disabled=no dst-port=53,5353 protocol=tcp

10.17.123.10 is IP address for cacti. Cacti need port 22 (ssh) and port 161 (snmp). Trust everything from 10.17.123.10.
add action=accept chain=input disabled=no src-address=10.17.123.10

And this is it, rules for IP addresses, 10.17.123.6. Users not need to know about this IP. But if one day users know about this IP address, we can identify who is connected to the IP address. There is a rule to the make records every IP address that accesses to the IP 10.17.123.6. According this results, we can analize IP address that should be blocked.

add action=drop chain=input disabled=no dst-address=10.17.123.6

Now about the security of the interface WAN. First, we limit IP address that will be connected to the router mikrotik. We just allow IP addresses that exist in half-trust group.
