Public bug reported:

This is observed in Gufw v14.04.2 LTS.  Creating a rule with a subnet in
the 'from' field of an advanced rule results in an error.

The example would be a requirement to only allow hosts in the same
subnet to have access to a particular service (e.g. RDP) and so the
'from' field would be set to a subnet of 192.168.0.0/24.

Attempting to add the rule results in an error in the log of "Error
running: ufw allow in log from 192.168.0.0/24 3389 > ERROR: Wrong number
of arguments".

Gufw appears to be trying to run the command: "ufw allow in log from
192.168.0.0/24 3389" which errors but compare this with the syntax of
ufw which would be "ufw allow in log from 192.168.0.0/24 to any port
3389".  This works successfully so it looks like Gufw is presenting
incorrect syntax for this configuration in this version.
