Ping's pass, but Traceroute doesn't pass the network of those years

The traceroute is probing, with a TTL of 1 and then ICMP sent to the first route. After a TTL minus 1TTL is 0. Returns information. Again ttl=2 hair. Click How to know is to reach the destination. Because UDP data was sent.
That is to say ping, ping is using ICMP, Traceroute is also. However, UDP is used in the back. The other end may have ACLs filtering UDP
A common one-way ping or a lot of this is an ACL issue.

The Tracert (trace route) is the routing trace utility that determines the path taken by IP datagram access targets. The Tracert command uses the IP lifetime (TTL) field and ICMP error messages to determine routes from one host to another host on the network.
Working principle and process:
The Tracert diagnostics determine the route to the destination by sending an Internet Control Message Protocol (ICMP) response packet to the destination with different IP time to live (TTL) values. Requires that each router on the path decrements at least 1 of the TTL on the packet before forwarding the packet. The TTL on the packet is reduced to 0 o'clock, and the router should send the "ICMP timed out" message back to the source system.
Tracert sends a response packet with a TTL of 1 and increments the TTL by 1 in each subsequent send process until the target response or TTL reaches its maximum value to determine the route. Route is determined by examining the "ICMP timed out" message sent back by the intermediary router. Some routers discard the TTL-expired packets without asking, which is not visible in the Tracert utility.
The Tracert command prints a list of the near-end router interfaces in the path that returns the ICMP timeout message in order. If you use the-D option, the Tracert utility does not query DNS on each IP address.
In the following example, the packet must pass through two routers (10.0.0.1 and 192.168.0.1) to reach the host 172.16.0.99. The default gateway for the host is the IP address of the router on the 10.0.0.1,192.168.0.0 network is 192.168.0.1.

The Traceroute program is designed to take advantage of the TTL (field) of ICMP and IP headers. First, Traceroute sends out a TTL is 1 IP datagram (in fact, each send out for 3 40 bytes of packets, including the source address, the destination address and packet issued by the time tag) to the destination, when the path of the first router (router) received this datagram, It will reduce the TTL by 1. At this point, the TTL becomes 0, so the router discards this datagram and sends back a "ICMP time exceeded" message (including the source address of the IP packet, all the contents of the IP packet and the IP address of the router), traceroute after receiving this message, Know that this router exists on this path, then traceroute another TTL is 2 datagram, found the 2nd router ... traceroute each time you send a datagram TTL plus one to find another router, This repetitive movement continues until a datagram arrives at the destination. When datagram arrives at the destination, the host does not send back the ICMP Time exceeded message, as it is already the destination, so traceroute how to know the destination arrived.
Traceroute when sending a UDP datagrams to a destination, the port number that it chooses to deliver is one that the general application will not use (more than 30000), so when the UDP datagram arrives at the destination, the host sends back a "ICMP The message of Port unreachable", and when Traceroute received the news, he knew the destination had arrived. So there is no daemon program on the server side of Traceroute.
traceroute extracts the IP address of the ICMP TTL expiration message device and makes a domain name resolution. Each time, the traceroute prints out a series of data, including the domain name and IP address of the routed device it passes through, and the three packets take time to go back and forth every time.
Traceroute has a fixed time wait response (ICMP TTL expiration message). If this time elapses, it will print out a series of * numbers indicating that, on this path, the device cannot emit the response of an ICMP TTL expiration message within a given time. Traceroute then adds 1 to the TTL register and continues.
