Hi all,
I have the following configuration:
Initial Situation:
Network 1: 192.168.0.0/24; Own internet access using Fritzbox 7490; Fritzbox IP 192.168.0.1; DHCP of Fritzbox is used
Network 2: 192.168.1.0/24; Own internet access using Fritzbox 7590; Fritzbox IP 192.168.1.1; DHCP of Fritzbox is used
Objective:
Connection of both subnets so that network resources can be shared (e. g. printer, NAS storage, etc.). Each network holds its own internet connection - internet connection should NOT be shared between both networks. Until today I used the integrated VPN feature of Fritbox - however it is a connection via internet and therefore very slow. I prefer a faster LAN connection as it is possible 
Background:
Connection of two separate houses next to each other via Gbit-LAN.
Hopefully the solution 
Mikrotik hEX S
Firmware Type mt7621L
Factory Firmware 6.41.3
Model RB760iGS
I did the following actions via Winbox:
Disabled ether1 - ether3
Disabled DHCP-Server
Disabled Firewall Rules
Configured ether4 with adress 192.168.0.254/24 network 192.168.0.0
Connected Network 1-LAN with ether4
Configured ether5 with adress 192.168.1.254/24 network 192.168.1.0
Connected Network 2-LAN with ether5
Removed all ports under bdrige
Route List:
[admin@MikroTik] > /ip route print
Flags: X - disabled, A - active, D - dynamic,
C - connect, S - static, r - rip, b - bgp, o - ospf, m - mme,
B - blackhole, U - unreachable, P - prohibit
DST-ADDRESS PREF-SRC GATEWAY DISTANCE
0 ADC 192.168.0.0/24 192.168.0.254 ether4 0
1 ADC 192.168.1.0/24 192.168.1.254 ether5 0
Problem:
I am not able to ping resources from network 192.168.0.0 to network 192.168.1.0 and other way round.
However, I reach both networks and resources via Mikrotik console:
[admin@MikroTik] > ping 192.168.0.1

4 192.168.1.1 56 64 0ms

I really hope somebody has an idea what to do
Best,
