Troubleshooting for some common problems when you install NxFilter.


When NxFilter not starting
When 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.
