ICMP Time Exceeded(超时)是ICMP(Internet Control Message Protocol,互联网控制消息协议)报文的一种类型,其Type字段的值为11。当IP数据包在网络中传输时,如果其生存时间(TTL,Time to Live)递减到0时仍未到达目的地,则路由器会丢弃该数据包,并向数据包的发送方发送一个ICMP Time Exceeded消息,通知发送方该数据包因...

I am getting an error on the router with line icmp time exceeded when ESP32 is replying to the master. The packet routes just fine to the ESP32 and to the master but it gets dropped on the router in between on the way back. Is there any way to increase TTL for modbus ? It does...
