+set sv_config "server.cfg" +set dedicated 2 +set net_port 27015 +start_map_rotate +set net_queryPort 27017

 

net_port

_net_queryport

 

etc i don't know i opened port 27016 UDP and TCP Both now what command line parameters must i use?

You first need to forward these ports

 

27017 UDP/TCP

27015 UDP/TCP

8766 UDP/TCP

 

Once you have forwarded those ports use

 

+set sv_config "server.cfg" +set dedicated 2 +set net_port 27015 +start_map_rotate +set net_queryPort 27017

Qury port must be one lower than net_port
