Troubleshooting for some common problems when you install NxFilter.
When NxFilter not startingWhen you find your NxFilter not starting, the first thing you need to do is to look into /nxfilter/log/nxfilter.log file. You can find some information about the cause of your problem. The other thing you might want to check would be port collision problem. NxFilter uses UDP/53, TCP/80, TCP/443 at default. This means NxFilter itself is a DNS server and a webserver. So, if you have another DNS server or webserver running on the same system, NxFilter will not start.
