Hello, I tried for several minutes to add my server but I can not do, in fact, it's a game call of duty MW3 at IP 109.70.148.135, then I have that information as:

+ set + set net_queryPort net_ip 109.70.148.135 27015 + set + set net_masterServerPort net_authPort 27,016 27,014 +

I tried everything but nothing works. Could anyone help me please?

You need to follow proper syntax in the command line. I do not know the correct way, but it should look more like this:

+set net_queryPort 27015 +set net_ip 109.70.148.135 +set net_masterServerPort 27016 +set net_authPort 27014

You shouldn't be mixing each command together, and you should not use commas. You should be able to find more info on this using Google.

Also, you need to open the appropriate port in the firewall so GameTracker can scan it.
