Routing between 2 Subnets

Hi everybody.
I must say: I am all new to MikroTik und worked with Cisco for years.
I have a very basic task but i am failing for days now and i am getting a little crazy…

I have to route between my network (192.168.1.0/24) and a new segment (192.168.2.0/24).
My Internet-Router is a AVM FritzBox. I added a static Route there: 192.168.2.0/24 is reachable via 192.168.1.254/24.

My attempt to configure the MikroTik hEX was:

/ip address
add address=192.168.1.254/24 interface=ether1
add address=192.168.2.1/24 interface=bridge1

/ip route
add gateway=192.168.1.1

At this Point i thought i would be able to ping the hEx Router on it’s ether1 Interface via 192.168.1.254 from any device in my Network. But the MikroTik Router does not respond. Also i am not able to Ping Devices on ether2 (where the 192.168.2.0/24 network is located.

Do i need to assign ether2 to the bridge? Why is the hEX not responding to ICMP requests?

Excuse me if these are very dump questions… but i am about to give up…

Greetings! Andreas


Edit:
When I assign 192.168.1.254 to ether2, the hEX does respond to pings… is there something special about ether1?

default built-in firewall rules and various settings deny access from wan interface (mostly ether1) to provide security in mos standard situations
