This covers incoming traffic being able to reach our container, but what about containers communicating with each other? In the diagram above you can see one container on the bridge network was started with the publish option (Container 2) and another which was not (Container 1). This is not a limitation of Docker but of IP networking in general. Note that you cannot publish to the same host port twice. ItвЂ™s not just that port publishing opens the firewall, but also that it creates a port forward via NAT into the Docker network. Since we published port 80 of our container to port 80 of our host machine, incoming traffic to our host on port 80 will be routed through the bridge network to port 80 of our container. Well, this would be true if we simply ran the container without using the publish option. So, although our containers can get out onto the web, no incoming traffic can reach our containers. The firewall on your host machine, by default, blocks all incoming traffic. This bridge network is automatically attached to the ethernet interface of your host machine so that containers can reach the larger network. When you start a new container and do not specify a network, it is attached to this virtual network. So what is going on here?Дocker has a default virtual network called the bridge network (identified as docker0). You should be able to see that the IP address of your container is not the same as your host machine. You can re use this command with format option to pull any information from a Docker inspect output but in this case we want the IP address from the network settings.Дocker container inspect -format '' testwebhost You could simply run docker container inspect and search through the output for the IP address. We can test this using a Docker inspect command. What about the containerвЂ™s IP address? You may think that containers use the same IP address as the host machine but that is not the case. You should now see that port 80 of your host is forwarding traffic to port 80 of the container. We can now list our port mappings for that container using: LetвЂ™s start off with a basic Docker command to run an nginx:apline web server container and forward traffic from port 80 of our host machine into port 80 of our container:Дocker container run -p 80:80 -name testwebhost -d nginx:alpine

Some basic understanding of networking (Nice to have, but not required).

In this blog post, we are going to dive into Docker networking and see what is going on in the background and why it is important. Docker utilizes a вЂњbatteries included, but replaceableвЂќ architecture meaning that the default network your containers connect to works well in many cases but can also be replaced with a custom network. When you start a container, you are also connecting to a specific Docker network. Well, if cavemen had computers of course. For NLA and SecureLayer the output was different and added the required changes to registry.Spinning up a Docker container is so simple that a caveman could do it.

Followed the steps given on and output is PASSED.

#Docker ip a windows

Verified No antivirus, windows firewall, security blockage.

Netstat -a shows that RDP is listening on port 3389.

Verified by sc query SessionEnv, sc query TermService, sc query UmRdpService, sc query RpcSs, sc query RpcEptMapper.

Surprisingly, The faulty server is able to reach other servers with ping and Test-NetConnection on port 3389.

For TCP, I checked with Test-NetConnection -Port 3389 and result was a failure.

Faulty server is not reachable from any other working server in the same subnet.

#Docker ip a serial

I am able to connect using Interactive Serial Console.

I had just rebooted the server and no other change was done. It was working till yesterday but today it is not working. My windows server 2016 is not connecting using RDP.
