Problem with "Wlan Bridge"

RouterOS Beginner Basics
1

Hello together,

first of all i must declare i really dont get the configuration of the mikrotik… i set up Firewalls like Fortigates very often but with this device i found my master :frowning:

So what i want:

i have a little Customer with a company LAN (nothing big)
now we want to set up the mikrotik that customers can get a wlan access to go to the internet by the mikrotik, the mikrotik should route his traffic to the router in the company but the both Lans (Wlan and LAN) should not communicate so the company data is safe..

i hope someone can understand what i mean… normally i thought this wouldnt be such a big thing, but i think i dont get how to config it with the mikrotik…

i have a rb751g with the 5.24. os

thank you very much

make a rule in /ip firewall filter.

match in interface wlan

match !wan

action drop

/ip firewall filter
add action=drop chain=forward disabled=no in-interface=wlan1 out-interface=!1-wan

The ! stands for not. So if the traffic is coming from your wlan and not going to the internet it should be dropped.
