The port 1,2,3,4 i put it in a Bridge but i have internet from DHCP 192.168.88.xx
How i can to do this ?

I’m not sure if I’m following exactly (perhaps a diagram would help). But broadly speaking:

  • Create a bridge for each network and put whichever ethernet/wireless ports in it that you want.
  • Use Mangle to create a Prerouting rule to create a routing mark and apply it to a bridge. (eg ‘/ip firewall mangle add action=mark-routing chain=prerouting in-interface=bridge1 new-routing-mark=routemark1’
  • Configure your firewall to allow or block traffic as required (eg, if I had an office and guest network, I might want office staff to be able to reach a printer on the guest network, but not the other way around)
  • Configure your routes. Also consider failover - I have a similar situation with 2 ADSL links. Guests use one, office uses the other, but if either goes down they can share a link.
