Mikrotik Yapılandırması
Router bağlantı noktalarına IP adresi vererek ve yönetilmesi daha kolay olan bağlantı noktalarını yeniden adlandırarak başlıyoruz..
/ip address
add address=192.168.0.1/24 network=192.168.0.0 broadcast=192.168.0.255 interface=LAN

add chain=srcnat out-interface=WAN2 action=masquerade

Lastly we need to add the DNS server that we can resolve hostnames
/ip dns set allow-remote-requests=yes cache-max-ttl=1w cache-size=5000KiB max-udp-packet-size=512 servers= 1.1.1.1,8.8.8.8
