e当连接空闲超时时。值范围：300~86400。te：此字段仅在选择“按需连接”或“手动连接”作为连接控制方案时可用。MTU 1。所需设置2。自动（0）默认设置为3。手动设置范围1200~1500 MTU指变速器单元。它指定允许Internet传输的最大数据包大小。当设置为“自动”（值“0”）时，路由器会选择MTU以提高Internet连接性能。NAT 1。可选设置2。默认情况下，在WAN连接上启用NAT（网络地址转换）。取消选中该框以禁用NAT.IIGMP 1。所需设置2。默认情况下，禁用设置为启用IGMP（Internet组管理协议），以使路由器能够侦听IGMP数据包，以发现哪些接口连接到哪个设备。路由器使用IGMP生成的接口信息来减少多址网络环境中的带宽消耗，以避免淹没整个网络。WAN IP别名1。可选设置2。默认情况下，复选框未选中启用WAN IP别名，然后输入服务提供商提供的IP地址。WAN IP别名由设备路由器使用，并被视为第二组WAN IP，为LAN网络提供双WAN IP地址。保存单击保存保存设置。撤消单击“撤消”以取消设置。EW200工业蜂窝网关40网络监控配置项值设置描述网络监控配置1。可选设置2。默认选中复选框选中启用复选框以激活网络监控功能。检查方法1。可选设置2。默认设置DNS查询。选择DNS查询或ICMP检查以检测WAN链接。使用DNS查询，系统通过向目标1和目标2中指定的目标发送DNS查询数据包来检查连接。通过ICMP检查，系统将通过向目标1和目标2中指定的目标发送ICMP请求数据包来检查连接。查询间隔定义两个DNS查询或ICMP检查数据包之间的传输间隔。加载检查1。可选设置2。默认选中复选框选中启用复选框以激活加载检查功能。启用加载检查允许网关在WAN带宽被完全占用时触发未返回的DNS查询或ICMP请求。这是为了防止错误的链接关闭状态。延迟阈值定义响应时间的容差阈值。Fail Threshold指定在路由器识别WAN链路关闭状态之前检测到的断开次数。输入检测到的断开次数作为断开阈值。查询间隔1。可选设置2。默认选择5秒。
ction when the connection idle times out. Value Range: 300 ~ 86400. te: This field is available only when Connect-on-demand or Connect Manually is selected as the connection control scheme. MTU 1. Required setting 2. Auto(0) is set by default 3. Manual set range 1200~1500 MTU refers to Transmission Unit. It specifies the largest packet size permitted for Internet transmission. When set to Auto (value ‘0’), the router selects the MTU for Internet connection performance. NAT 1. Optional setting 2. NAT is enabled by default Enable NAT (Network Address Translation) on the WAN connection. Uncheck the box to disable NAT. IGMP 1. Required setting 2. Disable is set by default Enable IGMP (Internet Group Management Protocol) to enable the router to listen to IGMP packets to discover which interfaces are connected to which device. The router uses the interface information generated by IGMP to reduce bandwidth consumption in a multi-access network environment to avoid flooding the entire network. WAN IP Alias 1. Optional setting 2. Box is unchecked by default Enable WAN IP Alias then enter the IP address provided by your service provider. WAN IP Alias is used by the device router and is treated as a second set of WAN IP to provide dual WAN IP address to your LAN network. Save Click Save to save the settings. Undo Click Undo to cancel the settings. EW200 Industrial Cellular Gateway 40 Network Monitoring Configuration Item Value setting Description Network Monitoring Configuration 1. Optional setting 2. Box is checked by default Check the Enable box to activate the network monitoring function. Checking Method 1. Optional setting 2. DNS Query is set by default Choose either DNS Query or ICMP Checking to detect WAN link. With DNS Query, the system checks the connection by sending DNS Query packets to the destination specified in Target 1 and Target 2. With ICMP Checking, the system will check connection by sending ICMP request packets to the destination specified in Target 1 and Target 2. Query Interval defines the transmitting interval between two DNS Query or ICMP checking packets. Loading Check 1. Optional setting 2. Box is checked by default Check the Enable box to activate the loading check function. Enable Loading Check allows the gateway to igre unreturned DNS queries or ICMP requests when WAN bandwidth is fully occupied. This is to prevent false link-down status. Latency Threshold defines the tolerance threshold of responding time. Fail Threshold specifies the number of detected disconnections before the router recognizes the WAN link down status. Enter a number of detected disconnection times as the threshold for disconnection. Query Interval 1. Optional setting 2. 5 seconds is selected by default.
