from LAN to LAN over bridge

Hello,

I have USG Flex700 and I am manging two different ISP networks withthe ZyWALL - one is main ISP and the other is of legally-established entity.
I was able to set it up with the great help of this community - via bridge as described within

The bridge is defined as follows:

Policy route:

Of course some demands happened later on to access some resources over that bridge.

One of them was to access internal web page which belongs to that legally based network.
So I have set the Policy Route:

and Policy Control:

and it behaves really nice - people form one subnet 192.168.0.x can access web interface 192.168.94.200 as HTTP/HTTPS without any problem.

Then another demand came - access data on Synology share which resides within network 192.168.0.x FROM network 192.168.94.x.
So I have followed similar steps:
I have defined the corresponding subnet as interface subnet over the mentioned bridge:

then Policy Route:

and then Policy Control:

But to access Synology in this direction, it does not work at all.

Please share your proposals, experiences, ideas.

Thanks a lot
