sv_maxPing — set maximum allowable client ping
sv_maxPing [ping]
sv_maxPing
sets the maximum ping in milliseconds allowable for a client, checked at time of connecting.
At connecting time the client ping is usually significantly worse than at normal gameplay,
therefore this setting might need to be inflated to compensate.
The server enforces this limit by rejecting client connections exceeding ping.
A value of 0 disables this functionality.
