Remote Monitor Ports

[reuben]

Is it possible to use the Remote Monitor/Remote Server through a firewall/router over the internet?

If so, which ports would I need to NAT to be able to do this?

[superflexible]

It needs an active CIFS connection, i.e. you need to be able to see the other computer in Windows Explorer and be able to access the other computer's shared drives etc.

CIFS is usually passed over the Internet thru a VPN only.

Documentation on CIFS ports can be seen here:
