Ok I think i solved the problem. Under firewall I have added rule to drop communication between two subnets, local subnet for office PCs and hotspot clients.

The best solution would probably be to put the ADSL modem in bridge mode then connect the RouterBoard such that the Hotspot is on one interface and the office switch is on another - then use Forward chain filters to ensure that traffic is permitted/denied as required. Can you please put some example?

Is your ADSL modem acting as a router with DHCP server? Can it be put in bridge mode so that the routerboard acts as the router/DHCP server?

Yes

Thx for help. After rebooting router everything started to work as it should. But I ve tried to connect on port 2 on router and everything also worked. Now I am confused why it is working on port 2,3,4 (interfaces 2,3,4), as on 1st, if I made VLANs on 1st interface (port1)?

Well I have DHCP servers created on each VLAN but I doesn’t generate address pools on those VLAN-s over manage switch. Like it doesn’t recognize that his port should act as trunk port connected on switch trunk port.
