Dynamic DNS (DDNS)
does not allow access to your router. What it does is associate a
domain-name with the public IP address of your router.
If your ISP will change your public IP in the future, you can keep
accessing your home via the name, which never changes, rather than
using the new IP address.
The No-IP account itself serves for nothing except allowing ...
It's quite possible that there is no access from the WAN side. Allowing it could be a serious security issue. You access it from 'inside'.
I don't even allow access over wifi on mine. You have to be in the building, connected to Ethernet to access it. That keeps it safe from fly-by attacks too.
I'd check the manual to see if it's user-configurable. I'd ...
Is there a way for me to, say, open up just one port, like 25565, and allow users to connect to my other minecraft servers, let's say hosted on 25566 and 25567 with subdomains?
This generally depends on whether the protocol allows clients to specify which domain they want (such as the "Host:" header in HTTP or the "Server Name Indication"...
After a little research I figured out that due to the fact I was using my university internet connection, my IP address was neither the one obtained by typing "what's my IP" on Google, nor my default gateway IP in the console.
According to the documentation on the service page of my uni router, it was my IPv4 address.
From there, I was able to send ...
In the AWS server, edit ~/.ssh/config to add the hostname 192.168.0.1
Port 52566 #Port used to ssh to the pi using reverse ssh
LocalForward 4444 192.168.0.1:4444
This makes the information in 192.168.0.1 port 4444 available in AWS port 4444
In the same AWS ~/.ssh/...
This answer is Unix-centric. ssh can be used in Windows. In Windows some concepts mentioned in this answer may not apply. Example commands use quoting and pathnames from the Unix world.
I use OpenSSH. Other implementations may miss some features this answer uses.

Assigning a static IP address to your Raspberry Pi will prevent this from happening,
First, edit the dhcpcd.conf file with sudo nano /etc/dhcpcd.conf
Scroll all the way to the bottom and add the following:
Replace the IP address, gateway and ...
SSH provides encryption for everything that uses a channel, in which the SOCKS functionality (as well as shell, port forwarding or SFTP) is wrapped. An SSH connection is made up of layers, which all have a specific function in the overall protocol. A simplified view for this example:
The transport layer (RFC 4253) provides encryption
The user authentication ...
If the remote_addr is always the router, the portforward you setup does a source-nat. For your purposes you only need a destination-nat, because the router has to take the traffic and route it to the new destination. It does not need to mangle the source if your old-laptop has a default route back through the router.
What consumers usually refer to as a ...
There is a common misconception about the IANA port registration.
The only reason this list exists is to avoid conflicts with
Nothing stops you from using any one port from the list if you have
not installed the software that uses it by default. And even then,
you may set that software to use another port (if possible).
I wouldn't advice ...
I have solved this myself in 3 steps. I'm going to post the answer in case this happens to anyone else. For this example, I have connected the Host OS' localhost:3000 to the server that is running on localhost:62094 on my Guest OS.
Step 0 - THE MOST IMPORTANT STEP
Make sure that your Guest OS has File Sharing or Network Discovery turned on. This is why I was ...
The question suggests that you're trying to access the guest from the host using IP address 127.0.0.1. This cannot work, 127-addresses refer only to localhost. I.e. from the point of both computer systems, host and guest, 127.0.0.1 = "myself".
You need to use the actual interface IPs. For example I have a VB VM running with a bridged adapter. My Wi-...
You're configuring the router using the UPnP IGD interface. It's most commonly used by programs to automatically set up port forwarding rules on startup, and so it is not unusual that routers forget those rules after reboot and/or after a certain period of time.
Instead, try adding the same rules through the router's webbrowser-based settings page – usually ...
