HUB_AO_UseHubNameAsDhcpUserClassOption この項目が 1 (有効) の場合は、仮想 HUB は DHCP サーバーに対して IP アドレスの取得を要求する際に仮想 HUB 名を DHCP パケットの "User-Class" オプションに埋め込むようになります。この機能は、複数の仮想 HUB がある場合に、DHCP サーバーがそれぞれの仮想 HUB 用に IP プールを確保する場合に便利です。(L2TP/IPsec および OpenVPN セッションのみ対応。)
|
||||
HUB_AO_UseHubNameAsRadiusNasId この項目が 1 (有効) の場合は、NAS-Identifier RADIUS 属性に仮想 HUB 名が埋め込まれます。この機能は、RADIUS サーバにおいて仮想 HUB ごとにアクセスの許可 / 拒否を設定したい場合に便利です。
|
||||
HUB_AO_AllowEapMatchUserByCert If you enable (set to 1) this option, the Virtual Hub will attempt to match the EAP Identity not only with usernames, but also with user certificates during the PPP EAP authentication flow.

HUB_AO_allow_hub_admin_change_option This is a special item. If you are enable (set to 1) this option, then not only the VPN Server's global administrator but also the Virtual Hub's administrator will be granted to modify the Virtual Hub Admin Options by himself.
|

HUB_AO_allow_eap_tls_match_user_by_cert If you enable (set to 1) this option, the Virtual Hub will attempt to match the EAP Identity not only with usernames, but also with user certificate CNs during the PPP EAP authentication flow.
|
||||
HUB_AO_deny_hub_admin_change_ext_option If you are enable (set to 1) this option, the Virtual Hub's administrator will be forbidden to modify any values on the Virtual Hub Extended Options, then only the VPN Server's global administrator can modify them.
|
||||
HUB_AO_no_delay_jitter_packet_loss If you set this option to non-zero value, then all parameters of delay, jitter and packet-loss on the access-list entry will be ignored even if these parameters are set when the administrator adds a new access list entry. Therefore, delay, jitter and packet-loss generating function will be virtually disabled. Because of the delay generating function sometimes make a high volume of load on the CPU and RAM, a Virtual Hub which is shared by several users should have this option enabled.
|

HUB_AO_max_users If you set this option to non-zero value, the maximum number of user objects registered on the Virtual Hub will be limited to this value, then greater number of user objects than this value cannot be added.
