if you install luci-app-pbr it installs at the same time pbr (certainly) with your preferred language option . you start pbr in luci and observe if the service gateways do not present a default.
to be certain of absence of anomalies, you pass in mod SSH and type "service pbr restart". green checkmarks appear and red checkmarks if there are defects.After the appropriate corrections everything must be green. enjoy it!
