As detailed on the original link at the top of this page, with 10.9 and earlier, you can run this command to configure ipfw to forward port 80 to. With 10.7, the preference was to use PF but the ipfw utility was still included with Mac OS. With earlier versions of Mac OS, ipfw was the primary way to handle firewall changes and port forwarding.

SSH port forwarding is a mechanism in SSH for tunneling application ports from. What's a port?You know when you call a phone number and the auto attendant picks up and says "Press 1 for sales, 2 for billing, 3 for support"? It's kind of like that.Every application which expects to receive requests from the outside world uses a designated port number so it knows how to handle that request. Perhaps you've tried setting up port forwarding but got stuck somewhere and don't get how it's supposed to be set up. You've probably heard you need to forward ports. But even though your PC has this private IP address, if you were to go to whatismyip.com, it would say your IP is the public IP instead of your private IP. Your PC is the only device in the world communicating with that IP address and any requests sent to that IP, your PC processes in some way.But you obviously have more than just that one PC you want to connect to the internet, and ISP's aren't going to hand out a public IP for every single device you have (we're just talking about IPv4 here), so you get a router.Now instead of your PC getting the public IP, your router gets it, and your router assigns your PC a private IP using DHCP, which we'll say is 192.168.1.10. So why would you have to forward a port?If you connected your PC to your modem (and the modem is bridged or not doing any NAT), your ISP would assign your PC a public IP address, which would look something like 93.184.216.34. If it got a packet to 31.13.65.36 :21, it would have its FTP server application deal with it.In our analogy, the phone number is like the IP and the option is like the port number. The server using 31.13.65.36 sees that request is on port 80, so it has its HTTP server application handle that request. For example 31.13.65.36 :80. ![]() It throws out that request and sends back a TCP RST to whoever made the request in the first place. But it doesn't work.What's happening is the HTTP request makes it all the way through the internet and once your router gets it, it says "Hang on, I'm not running any application using port 80". So you go to whatismyip.com and you get your public IP and you tell all your friends to visit. If you were to host a website on your PC, your HTTP server application would expect to receive requests on port 80. What was that about the static IP?Right, so normally when a device connects to your router, your router uses DHCP to assign it an IP from a pool of addresses and the device can use it for a period of time. Protocol: TCP (HTTP uses TCP instead of UDP, but most of the time you have the option to select both if you're unsure, but that's beside the point)In the end, your routers setting may look like this:Note that there are a lot of extra options here which are not needed and should be left blank. Internal IP: 192.168.1.10 (your PC's internal IP address, which is good practice to configure with a static IP) We can move on to troubleshooting. Ok, I did all this and it's still not workingThat's fine. Be aware that means the device in the DMZ is getting all the garbage your router doesn't want, so you'll want to make sure whatever device in the DMZ has proper updates and security. Essentially when you put a device in the DMZ, your router will forward any traffic it doesn't know what to do with to the device in the DMZ instead of just giving up and throwing it away. So what if I used a DMZ, I've heard I should do thatYou could do that instead of port forwarding. You'll want to check the range of IP's your router is handing out and pick something outside it (for example, if DHCP is configured to hand out 192.168.1.10 - 192.168.1.254, you may want to configure the PC to use 192.168.1.5 since it's not an IP your router will try to hand out and cause an IP conflict). At the bottom you'll see "Listening Ports". You could also search for "Resource Monitor" on your system.Once this is open, go to the "Network" tab. We'll focus on how this is done on Windows.Open the Task Manager and under the Performance tab, click "Open Resource Monitor" at the bottom. Parallels for mac online downloadAfter that, you may need to start looking at your ISP to see if they're blocking certain ports. Also make sure your router isn't also doing some firewall filtering. If the result shows the port is blocked, first, doublecheck your work. The application is listening, my firewall isn't blocking it, but it's still not workingAt this point you should go to a website like yougetsignal.com to do some external testing. If it is in this list, but "Firewall Status" says "Not allowed" or "restricted", then you'll need to create an exception in Windows Firewall for that application (which is outside the scope of this discussion). You can use multiple routers this way, but you'll want to make sure everything is only connected to the LAN ports on the second router doing the WiFi extending (disable DHCP on the second one too). Usually when people have more than one router set up in their home, they're trying to extend their WiFi. If you're connecting through more than one router, you may be double-NATting yourself. Because of this, you're essentially double-NATed and it makes it impossible for you to port-forward from your router.There are complicated ways around this (VPN to a VPS), but you may want to ask your ISP if they offer a static IP which isn't CGNATed. Essentially they don't have enough IPv4 addresses for all their customers, so they're doing NAT themselves to allow more customers to connect. If your public IP is something between 100.64.0.0 and 100.127.255.255, your ISP is using Carrier Grade NAT (CGNAT). That's fine, right?No, it's not fine at all. On the isp router/modem combo box, set a dmz to the 2nd router.
