This NAT rule completely breaks SMB file sharing ...

Escape75

I have the following LAN setup on bridged ports on my UTM:

So far so good, then I added a 2nd IP to my LAN so that I can access a device using that subnet (when this device is reset it goes to that IP):

Now comes the weird part, I've added a NAT rule so from 192.168.5.x subnet I can access 192.168.50.x:

And when this rule is enabled, it completely breaks SMB file sharing on 192.168.5.x network ...

Any ideas, how I can achieve what I need and replace this rule with something that would work ?

    I don't see the logic behind the masquerading rule.   A simple firewall rule should be all you need and maybe disabling the firewall on the device in .50.x.

    You're right, the NAT rule isn't needed and it still works without it,
    however I still wonder why it's causing file sharing issues, and network discover issues ...
