user35343: Good Evening,
I recently installed Bitcoin Core v0.12.1 on my home server (running Windows 7) and wanted to allow it to accept incoming connections and used the guide found here: https://bitcoin.org/en/full-node#windows-7 to ensure I did everything that was needed.  Unfortunately, it hasn't been showing any incoming connection and when I used the connection tool recommended in the guide (https://bitnodes.21.co/#join-the-network), it says my server is unreachable.
I have already setup port forwarding for port 8333 to both my server's IP address, 192.168.1.105 (wireless) & 192.168.1.129 (ethernet).  I ran a port scan on the following websites and they all indicate that Port 8333 is open:

Ping.eu Port Check
WhatMyIP Port Scanner
T1 Shopper Port Scanner

(I would provide links for the above scanners, but I cannot post more than 2 links)
I also created two rules in Windows Firewall (under Inbound Rules) with the following properties:

Local Port - 8333
Remote Port - All Ports
Scope - Local & Remote IP address set to Any IP Address
Domain, Public, and Private all checked
All programs that meet the specified conditions checked
Set to allow the connection
Rule is enabled

There are two rules with the above settings, one for TCP and one for UPD.  Even with all the above setup, the "Join the Network" tool on Bitnodes website (second link from the top) still says my node is unreachable and the debug window inside the program shows 0 incoming connections and 8 outgoing connections.
I'm not sure what else needs to be setup since I completed everything in the guide and port 8333 is definitely open.  Any help or information with this issue would be greatly appreciated.  Thank you in advance.

user85016: I had the same problem after following all of the usual steps. I waited and it still didn't work. I had to change my computer's firewall (in the Inbound Rules) for the Bitcoin Core (highlighted one below) to have a Private Profile. It was "Private, Public" at first. 

You can see if you have both directions working from this icon. Both parts of the U's to the left of the check mark below should be bold. If one of the directions isn't working, it won't be a bold line. 

Also you can change the maximum number of connections here:
Bitcoin Core - Wallet > Settings > Options > Open Configuration File
I think mine was only set to max=3 at first.

user45161: I had the same problem. The port was open, but the test at bitnodes.21.co would fail. However after my Bitcoin client downloaded the entire BlockChain everything worked. I used about 144 hours to download the entire chain with a 150Mbps fiber line.
Before the entire chain was downloaded the test at https://bitnodes.21.co/#join-the-network would give an "Unreachable" error. After it downloaded it changed to Green saying it's reachable.
So you just have to be patient :)
