I am running windows on 192.168.31.4, 192.168.31.8 and 192.168.30.198

I can access shared drive between 192.168.31.4 and 192.168.31.8
But can't access shred folders from 192.168.30.198

Please help me on this,

Thank You so much!

Default Windows firewall allows access only from same subnet. Clean solution is to allow access from the other one (on target machine). Lazy solution is to add srcnat rule, which will make all connection from other subnet look as is they come from router, which is in same subnet.

3

Additional complication is (or was at least, it’s been ages since I had to deal with this crap) that windows uses broadcasts for detection of other machines on the network if domain controller is not available. Broadcasts don’t pass routers.

Thank You so much brother its working now,

Yes I can’t see shared drives on network places,

Windows uses broadcast to find others SMB shares - but You can just point it to one machine, and it will work - broadcast or not.

So, You can just type the FQDN of the machine you want to access, and windows will open it. Then, if You map this share, it will work just fine.
