So I tried to ssh my home machine over Termius ios, but it can only be done inside the WLAN. Here’s the information on dynamic port forwarding.
I had enable port forwarding on my router as well as Gateway Ports yes on my ssh config. Is there anything else I shall try ?

I host a personal server at home, behind my home router. When attempting to connect with SSH from internal network, it works fine. From outside my home networks, it happens... nothing.
From internal : ssh user#internal.ip -p custom_port => prompts for
password and connects
From external : ssh user#router.ip -p custom_port => cursor blinks
a little, then nothing. No timeout. I have to ctrl+c to quit
Do you have any idea about how I can solve this ?
Confugation
Serveur : Debian 11
SSH with custom port
iptables allows the SSH custom port + no-ip required ports
Router : NAT configured with the custom port
External IP : either router's IP, or no-ip tld
Router's port forwarding seems OK
I am certain that the server is reachable. I used PortCheckTool:
shows "port open" when the server is up
shows "port close" when the server is down
So the NAT/port forward seems to be OK
It looks as if the server's reply is bocked, but I don't know how to check
I am not a pro admin, so I don't know how to check
if server received connection requested
sent a reply
if the router's firewall blocks the reply
I just checked my router. Firewall enables "all outbound traffic except netbios services".
Update
I found the auth.log file. I cannot find the attempts to connect from outside (no "invalid" entry, nor entry for the related times ).
I'm developing some webhook required direct access public domain to internal machine, thinking use SSH tunnel to forward data, or got alternative solution?
Hosting server & development machine are in same network
192.168.1.2/24 (Hosting server)
2nd machine is virtual mapping using forticlient firewall without static or dynamic IP in visible in hosting server, so is 1 way initial communication right now.
In this case possible to setup SSH tunnel forward all traffic from 192.168.1.2:80 to handle in development machine port 8080?
How to ssh syntax look like?
Thanks.
This could be done by setting up an SSH tunnel to the remote machine:
ssh -L localhost:80:localhost:8080 development-system
Every request to port 80 on the hosting-server is now forwarded to port 8080 on the development-system.
Please note, that the port 80 on the hosting-server could only be used, when you start the SSH command as root. Also note that the port 80 is only accessible from the hosting-server. To access the port 80 on the hosting-server from everywhere use the following:
ssh -L 80:localhost:8080 development-system
Be sure that you want that.

I have a Ubuntu Server 16.04 running on a machine in my local network.
The machine has static assigned IP and running apache2. There is no problem in connecting to it from my local network.
I have port-forwarding for ports 22 and 80 setup on my router to the IP address of the machine.
When I check the ports with my public IP address on sites like http://www.canyouseeme.org/ the result is that the ports are open. When I try to connect using my public IP address and using those ports the connections are refused.
I tried disabling firewall in the router and also on the machine, no result.
What else should I try? It seems that the server is getting no incoming connection when I check with netstat.
Just for troubleshooting purposes:
Setup port forwarding on port 22 and try to ssh into your server using the public IP? If it works, it means apache is refusing the connections and not your router or ISP
On your router, setup the server on the DMZ temporarily and check if it works
Add another port forwarding rule on your router to redirect all http requests on port 8000,for example, to port 80 internally, then try to access your server with http://[public_ip]:8000
Have you changed anything on the apache2.conf file? Also, explain how you are testing the connection, internally using the public IP or from the Internet?
Okay, here's the situation I am in. I have a raspberry Pi 2 model B. I have Raspbain Jessie installed as the OS. I have Apache installed as well. I have a web server running and i am able to edit it and access the site from different devices on different internet connections. I want to be able to connect to my RaspPi through SSH on my MacBook Pro. I am able to do this while on the same network. My Pi is plugged into the router via an Ethernet. What i have tried is, logging into my router and reserving an IP for my Pi, i also entered my MAC address here. I have gone into the port forwarding options in my router and have it set up as: HTTP, TCP, Server address(the one i reserved) my Ipv6, and Start port 80, end port 80. Ontop of that i have gone into my /etc/dhcpcd.conf file. There at the end of the file i added
interface eth0
static ip_address=10.0.0.100
static routers=10.0.0.1
static domain_name_servers=68.44.180.118 2001:558:feed::1 2001:558:feed::2
The guide I followed is attached here and follows other guides i have seen.
http://www.circuitbasics.com/how-to-set-up-a-static-ip-on-the-raspberry-pi/
Yet when i try to SSH remotely i cannot get a connection, and when i connect on the same internet i can connect as normal. Please if anybody sees what could help .
Your router's firewall is probably blocking the ports for SSH, which does not use port 80 (in raspbian, I think its default is port 22). If you are going to take the risk of leaving your SSH open to the public, you should probably switch it to a different port other than the default before opening up a port on your firewall. The Raspbian Community has a thread on how to properly change SSH's default server port. You'll also need to make sure your SSH client is using the same port. You will need to leave 80 open for web, and also forward the SSH port, which ever you choose that to be (22 is the default).
I have to set up a Virtual Machine on vBox that works as a server for my app. Now, the app sends data to http://x.y.w.z:4567. I run apache server on host and wireshark confirms that the packet is received. Guest is behind NAT and is set up to forward TCPs from any IP port 4567 to port 443 on guest. I tried various versions of setting and not setting IP. Guest also has apache running, but it receives no packets. What should I do?
Please check the log that your port-forward rule is active. Also that your guest/host firewalls doesn't drop packets.
