You may block domain, ip's and ports
IP's:
https://www.whatsapp.com/cidr.txt
Ports:
TCP 5222
TCP 5223
TCP 5228
TCP 5242
Domains (How to block a domain w/ Windows Firewall):
whatsapp.com
whatsapp.net

I need some help understanding the current situation that I am having with my home network.
My home network is very simple: My ISP is xFinity with a Dynamic IP that doesn't change very frequently. Last IP change occured 6 months ago. It comes into an Arris SB6183 modem that I own. From the Arris, it goes into a Linksys E8540 WiFi 6 Router (or a Netgear R6250 DD-WRT due to troubleshooting). From here, I only have 2 computers: one Linux Desktop, and one personal Windows laptop that I use for web-browsing.
The Linux Desktop machine (LAN IP is 192.168.1.200) has SSHD Service on Port 22. The Router port forwards incoming SSH 22 connection from Internet to Port 22 on 192.168.1.200. Router firewall (SPI) is disabled.
Everything stopped working about 2 weeks ago. I am not able to SSH from outside into my Linux Desktop machine. If I am on the internal LAN, then SSH works just fine.
Using CanYouSeeMe.org shows me that Port 22 cannot connect: "Reason: connection timed out"
Here is what I tried:
Removed the Router and Laptop and plugged in the Linux Desktop
straight into the Arris modem. SSH attempts still shows "Request
timed out"
Made sure that UFW Firewall on Linux is off. No Fail2Ban.
Replaced the Linksys E8450 with Netgear R6250 DD-WRT. No change.
Called xFinity Customer Support and asked "Is Comcast blocking external incoming IPs to Port 22 ?" they responded "We don't block Port 22"
Contacted Comcast Customer Security Assurance and Abuse and asked them to verify if my profile has some Security Profile/Screen in place or some sort of flag. They responded NO.
Then, finally I put a Port Forwarding rule on the router: incoming connection on port 2222 go to SSH 22 on Linux Desktop. And this works!! If I initiate external SSH connection attemps on port 2222 I do indeed connect to my Linux desktop.
In a related news, my Reolink Security APP on my Android Samsung phone no longer connects to my Home Camera over Cellular Data. It connects fine if my Phone connets to the Lan over WiFi.
What are your thoughts ? Does it look like my ISP is blocking incoming connections ? Any help greatly appreciated!
I have a workstation with Win 10 on which I installed OpenSSH server. If I try to connect to it (from another machine with Win 10 using ssh in a command prompt) I see it gives the following error:
ssh: connect to host Test3 port 22: Connection timed out
On wireshark Syn packets are sent but no answer is received back.
If I dissable Windows firewall on destination then connection is established.
I want to leave the firewall enabled and disable only ssh port.
You can easily use netsh.exe.
netsh advfirewall firewall add rule name="Open SSH Port 22" dir=in action=allow protocol=TCP localport=22 remoteip=any
You can also change remoteip to a specific host:
remoteip=any|localsubnet|dns|dhcp|wins|defaultgateway|<IPv4 address>|<IPv6 address>|<subnet>|<range>|<list>
I found on microsoft site a link which allow to do it using graphical interface.
I solved my problem performing the following steps as administrator:
Open the Group Policy Management Console / File/ Add snap-in / Windows Defender Firewall with Advanced Security(or Windows Settings/ Windows Defender Firewall / Advanced settings).
Inbound Rules / Actions / New rule
Rule Type / Port / Next
TCP / Specific port: 22 / Next
Allow the connection / Next / Next
Name / Open ssh port 22 / Finish
I'm setting up a new server 2012 R2, and want to be connected to it remotely using an IP address or a domain name.
Read your modem's/gateway's manual and learn how to forward ports
Forward ports 8069 and 8072 to your windows server
Visit https://www.whatismyip.com/ or any other service that tells you your public IP address
Open your browser and go to http://<your_public_IP_address>:8069
I have a java program that uses SQL queries. The goal is to send them from my home PC to a workstation on a different network elsewhere.
The SQL server is on Windows Server and I opened port 1433 for inbound connections. From that computer, I can successfully ping the port. However, I can't ping the port from the public ip address, only the local (192.168...), so it doesn't work if I were to try to ping it from my home computer.
Is there a way that I can ping it from my home computer? If so, how would I specify the address for JDBC?
Thanks!
It sounds like your Windows Server is behind an internet gateway/router. You need to configure the gateway to allow and forward inbound connections to TCP port 1433 to the IP of the computer that has SQL Server installed.
Here are some guides that explain how to enable port forwarding on different devices:

Also, note that we can ping IP addresses, not ports.
Device: Raspberry Pi 2 Model B
OS: Raspbian Stretch ( no desktop ) with static ip
Router: Belkin F9K1103
DNS service: Hosting on Norwegian version of domainnameshop.com
Greetings. I'm in the process of setting up my Pi as a server. The current motive is to be able to ssh into the device from another network and host a Git server on it.
It works great at home using the local ip address, but when it comes to port forwarding port 22, NOTHING works... I've tried for at least 10 hours combined, scavenging the internet for solutions on this topic, rasbian / raspberry related port forwarding or general. Nothing seems to work. I've tried everything it seems, and no matter what i do the tests show that the port is CLOSED.
I'm currently port forwarding the Pi's local ip and port 22 on the networks port 22 ( also tried port 3322 to the pi's port 22 ) on BOTH the router and the modem using the internet provider's own service for port forwarding online ( Telenor ). The Pi is connected with an ethernet cable, and I've tried connecting it to both the router and the modem when doing all the tests. I've also tried to add 'Port 22' and 'Port 3322' in the Pi's SSH configuration file.
I've also tried to use a DNS service in which I'm forwarding my home network's ip address but still no luck.
Can anybody please help me before I go insane? I'm I missing something crucial? I can't count on both my hands how many forum posts I've been reading and guides on both raspberry or general port forwarding..
Ok so I found out what was wrong.
Our modem is quite new and advanced, and the internet provider has their own online admin panel for it with its own port forwarding solution and what not. So this was apparently a case of classic double NAT conflict. The router tries to port forward to the modem which would normally just bridge that onto the web, but the modem is in a sense being port forwarded too by the internet provider and it's own services.
What I had to do was reverting the static IP configs on the Pi, unplug it from the wifi router, then plug it directly to the modem and then port forward it using our internet providers online admin panel for the modem.
Now it works brilliantly.
