In one network I have two Mikrotik routers with two IP addresses:

MikroTik1: WAN -> 194.141.118.46 -> DHCP on PC1 -> 192.168.0.2
MikroTik2: WAN -> 194.141.118.47 -> DHCP on PC2 -> 192.168.0.2

When PC1 shares a directory, it cannot be mapped to PC2 like: \\194.141.118.46\Map

When PC2 shares a directory, it cannot be mapped to PC1 like: \\194.141.118.47\Map

Settings in MikroTik1 is:

# dec/20/2023 15:46:46 by RouterOS 6.47.10
# software id = CGUK-AFJL
#
# model = RB952Ui-5ac2nD
# serial number = CC460EF3AC25

The ideal would be a LAN with different networks; LAN1 192.168.0.0/24 LAN2 192.168.1.0/24 a connection between routers to have access using L3 Router.

I have never tested SMB redirection in NAT but I believe that the IP is arriving at the PC as its own IP. Do a masquerade and it should do the trick.
on both routers
