Cannot add rule for NFS (Chris Lowth)

[edice]

I can't add a rule based on the "NFS (Chris Lowth)", limited to just one interface.

The Advanced pane disables the Add/Apply button.
I guess because the port range includes a : range,
and I've read elsewhere that the "Protocol: Both" should be set to TCP or UDP,
but that dropdown is disabled and can't be changed.

There seemed to be no way to fix the rule, and in the end I had to make the rules manually.

Hi, right, you can't add it because of some parameters. Please, play with them, until the Add button would be enabled. Best regards.
