Question about Zyxel P660HW-D1 Router

Port forwarding not working in ok firmware AGL6 or later

Port forwarding not working in firmware after AGL.4. Something wrong with the firewall. Everything works fine in AGL.4 but with firmwares AGL.6 and AGL.7 the port forwarding through the firewall doesn't work. Disabling the firewall and it works. Zyxel's support in northern Europe refuses to acknowledge this problem, so had to do a rollback to AGL4...

I'm just doing a basic port forwarding NAT + RULES in the firewall. No access from WAN to LAN to my IP-cameras. As said above with AGL.4 everything works fine...

According to my very thorough testing some weeks ago, P-660-HW-D1 port forwarding is really very broken.

The worst thing is that not only does the port forwarding work properly, it lets packets to LAN addresses where they're not supposed to go. This means you're not safe behind LAN.

Firewalled or not, AGL.6 or AGL.7 shouldn't be used at all in my opinion, they're unsafe. When in routing mode, and having several LAN machines behind one Zyxel switch port (i.e. separate switch attached), I found that the port forwarding is completely broken.

I have contacted Zyxel Finland about this issue two weeks ago, and they initially thanked for the finding and said they're passing the issue onwards and investigate it.

The best current solution is to downgrade to (also very buggy) AGL.4.

Solution for War Craft 3 behind Linksys routers.........


As the application requires certain ports to be opened on the router,try to follow the steps below to configure the router. Since you are connecting behind the router, you are going behind a NAT firewall.Therefore, you would need to allow ports for the remote access application to go through the firewall. You would need to know what port number application uses. You can check with the program manufacturer for the information, or see the Help menu.


For routers with old firmware versions (without the Cisco web interface):


1.Open Internet Explorer.
2.After "Internet Explorer" opens, please typehttp://192.168.1.1 into the "Address Bar" and click GO.
3.The "Enter Network Password" window will appear. Skip username and type admin (admin is the default password) as the password,and click OK.
4.You will need to click on the Advanced tab to the very right. Once the "Filters" area appears, please click on the Forwarding tab.
5.Once the "Forwarding" area appears, click the Port Triggering button. Once you've done this, a new window will appear.Enter the ports needed to be opened > Click Apply


For later firmware (that has the Cisco web interface)


1.Open Internet Explorer.
2.After "Internet Explorer" opens, please typehttp://192.168.1.1 into the "Address Bar" and click GO.
3.The "Enter Network Password" window will appear. Skip username and type admin (admin is the default password) as the password,and click OK.
4.Click on "Applications and Gaming" then click on the "Port Triggering" Sub tab. Enter the ports needed to be opened >Click Save Settings.


Example:

Customized Trigger Port Range Incoming Port Range
Application From ~ To From ~To
WARCRAFT 6112-6112 6112-6112
WARCRAFT 6113-6119 6113-6119

Hope this help everyone that has problem with the game.

My F5D7230-4 Belkin Router Virtual Servers power forwarding broke


Hi there!

Have you checked the Windows Firewall settings? If it is On, try turning it off and attempt the connection with RealVNC. If the problem persists, try adding an Exception to the Windows Firewall, just as an added troubleshooting measure.

Click Start, navigate to Control Panel, double-click Windows Firewall, and open the Exceptions tab. Look for a RealVNC entry. If you don't see one, click the "Add Port" button, type RealVNC as the entry name, and 5900 as the port number. Select the TCP radio button, click OK and then OK once more. Attempt the RealVNC connection again.

I hope this helps! Feel free to reply with results or further questions.

Port fordwording is not working for Radmin port 4899


when you do port forwarding you must know or have a static ip of the device for the application. For example, if you want to forward port 3074 for your xbox live, you need to enter also the xbox ip address on the port forwarding page. Port forwarding is like opening a port on your firewall for that specific application. Make sure also that you have the latest firmware of the router.

Port Forwarding


Port forwarding is a method that allows you to run a server behind the router. Port Forwarding opens a specific port to a computer behind the router, allowing all Incoming Traffic on that port to be sent directly to that server. It should be used to setup servers behind the router, typically Port Triggering (Answer ID 344) is a better choice for non server applications (Such as instant messengers and game servers). Below is an example of how to setup Port Forwarding. For our example we will be setting an FTP Server and a Mail Server that uses SMTP and POP3. FTP uses ports: 20 and 21 SMTP uses port: 25 POP3 uses port: 110 Getting Started 1. You must set a static IP address on the server. If you're unsure of how to do this please go to Answer ID 534 for information on setting a static IP address in Windows. 2. Once the static IP address has been assigned please go to your desktop and double click on Internet Explorer (Located on the Start Menu in Windows XP) 3. Once "Internet Explorer" opens, please type http://192.168.1.1into the "Address Bar" and click GO 4. The "Enter Network Password" window will appear. Skip user name and type admin (admin is the default password) as the password, and click OK 5. This will bring up the routers "Setup" section. Look under "Domain Name" and check what version of the firmware you're using. 6. You will need to click on the Advanced tab to the very right. Once the "Advanced" tab comes up please go to the Forwarding tab. Firmware prior to 1.32 This will not work with firmware prior to 1.32 Firmware between 1.32 and 1.36 Service Port Range 20 ~ 21 25 ~ 25 110 ~ 110 IP Address 192.168.1.3 192.168.1.3 192.168.1.3 Firmware after 1.36 up to 1.40m Service Port Range 20 ~ 21 25 ~ 25 110 ~ 110 Protocol Both Both Both IP Address 192.168.1.3 192.168.1.3 192.168.1.3 Firmware after 1.40m Customized Application FTP SMTP POP3 Service Port Range 20 ~ 21 25 ~ 25 110 ~ 110 Protocol Both Both TCP IP Address 192.168.1.3 192.168.1.3 192.168.1.3 Finishing up Click Apply, then Continue Restart your computer
