Port isolation on bridged ports?

RouterOS General
1

Hi I’m running RB1200 and I’d like to do like this:
Port 1: WAN DHCP Client
Port 2-10: Hotspot LAN (all bridged) to Port 1

The rules are:
Port 2 can talk to port 1, but can’t talk to port 3 4 5 6 7 8 9 10
Port 3 can talk to port 1, but can’t talk to port 2 4 5 6 7 8 9 10
Port 4 can talk to port 1, but can’t talk to port 2 3 5 6 7 8 9 10
Port 5 can talk to port 1, but can’t talk to port 2 3 4 6 7 8 9 10
Port 6 can talk to port 1, but can’t talk to port 2 3 4 5 7 8 9 10
Port 7 can talk to port 1, but can’t talk to port 2 3 4 5 6 8 9 10
Port 8 can talk to port 1, but can’t talk to port 2 3 4 5 6 7 9 10
Port 9 can talk to port 1, but can’t talk to port 2 3 4 5 6 7 8 10
Port 10 can talk to port 1, but can’t talk to port 2 3 4 5 6 7 8 9

Is it possible to do that?

Note: I’m currently using Port 1 as WAN, Port 2 as Hotspot LAN, Port 3-10 wasted, then go to managed switch for port isolation.

Use the split-horizon feature to accomplish this:

http://wiki.mikrotik.com/wiki/MPLSVPLS#Split_horizon_bridging
“The basic idea of split horizon bridging is to make traffic arriving over some port never be sent out some set of ports.”
“Bridge horizon feature allows to configure bridge ports with horizon setting so that packet received over port with horizon value X is not forwarded or flooded to any port with the same horizon value X”

So for you:
Set horizon of each ether port in the bridge to the same value.

Thanks for the information. I’ll try it at my next maintenance :smiley:
