Windows share between two routers

I am having a local network of ip pool 10.10.190.0/24. Which is assigned in one of main routers which is CCR-1009 located in my officeas LAN I have assigned a ip(10.10.190.189) to my windows 10 pc to access windows . If I connect through another laptop which is located In my home on same local network and assign a ip 10.10.190.190. I can access windows share and my laptop network discovers windows 10 shared files and folders. And when I try to connect through my another rb450g router and assign same local ip 10.10.190.190 as wan(ether1) link on rb450g ether2 as LAN I was not able to acess windows share. I am able to ping 10.10.190.189. I tried dsnat but No luck.. any ideas

mnsra92,

I’m not sure if you checked, but because it sounds like you’re trying to connect across a routed network in your second scenario I believe that a firewall rule may be the issue. According to the Microsoft documentation for SMB and CIFS in an article titled “Service overview and network port requirements for Windows” on the Microsoft support site you should enable ports for UDP 137 and 138, and TCP 139 and 445. I wish I could write the firewall rules for you and paste them here, but I am out of practice. Let me know if this works.
