Each port of mikrotik is separate from others

[alharbi]

Hi every body,
I searching how to setup a mikrotik router act each port a separate from the other ports and each port will get extern dhcp ip from other network, all port can communicate with one port in the same device for transmit data.
Any body know who i should start or a solution
Thank

Can you draw a diagram so its a little clearer,

So you are looking for something like “(Private) VLAN” ? You want to avoid that each of the ports can communicated among them ?
But please explain your usecase ? Are you offering something like Internet access for an apartment building where everybody has their own router ??
Where are all the different DHCP-servers located ? Who is facilitating/managing these ?

There are probably several solutions possible.

Default setting on SOHO Mikrotiks is to have ether2-etherX (where X is the last ether port, mostly that’s ether5) in a bridge which means these ports act as being part of a switch. If you want to assign individual IP addresses to each of ports, then you have to remove ports from the bridge. Doing it it may break your management connection to the router if you’re connecting over IP (ssh, telnet webfing, winbox over IP address), so it’s highly advisable to connect using winbox over MAC address when doing it.

After you assign separate IP addresses to each of ports, you have to adjust firewall rules to block (or allow) traffic between those ports according to your wishes.

Not a simple task if you don’t have at least some experience with networking.
