<li>sv_rehlds_stringcmdrate_burst_punish // Time in minutes for which the player will be banned (0 - Permanent, use a negative number for a kick). Default: 5
<li>sv_rehlds_userinfo_transmitted_fields // Userinfo fields only with these keys will be transmitted to clients via network. If not set then all fields will be transmitted (except prefixed with underscore). Each key must be prefixed by backslash, for example "\name\model\*sid\*hltv\bottomcolor\topcolor". See [wiki](https://github.com/dreamstalker/rehlds/wiki/Userinfo-keys) to collect sufficient set of keys for your server. Default: ""
<li>sv_rehlds_attachedentities_playeranimationspeed_fix // Fixes bug with gait animation speed increase when player has some attached entities (aiments). Can cause animation lags when cl_updaterate is low. Default: 0
<li>sv_rehlds_maxclients_from_single_ip // Limit number of connections from the single ip address. Default: 5
