Free Dynamic DNS Service Site -

Duck DNS is a free dynamic DNS hosted on Amazon EC2.

To get it working is quite easy. Add a sub domain and update your current ip address to it.

In above screenshot, I created as a DNS to point to my home network ISP ip. 

On one of my home internal machines, just installed a client to update the ip on this dns name dynamically. The DuckDNS settings is shown in below screenshot. Put into your sub domain name and token. After all done, just click ok button, then it will automatically update it every 5 minutes.

TekRADIUS Usage for AD Authentication

TekRADIUS is a RADIUS software which can be easily integrated with AD. I have tested on one of pc , which even it is not in the domain. But AD authentication is still working, but not with group property.
Here are some configuration settings:

I set up two groups. One is admin group with privilege 15. Another is admin-read group.
 Authentication-Method, I select Active Directory with server ip
 Clients is default, which means any. Secret is cisco.
 Please make sure Vendor ID 42214 kaplansoft is in this dictionary editor. The version I download from website is not including this. I requested it from the discussion board.
 Authentication port is set to 1812 and Accounting port is 1645. debug logging is for troubleshooting, although not too much info in there.

Configuration on the Radius Clients:
1. Checkpoint SmartDashboard: host_mgmt_1 is the RADIUS server ip address.
Create a new administrator with exactly same name as your AD account. Of course please choose authentication method as RADIUS.

2. Juniper NSM:

Similar as checkpoint configuration. Create a new authentication nserver then add a same ad name account with Remote authenticated.

Configuring Polycom Video Conference System - HDX 8000

My company is using Polycom solution to provide video conference for all branches. Recently there is a issue which one way video and audio from my site. What I found trick part is the firewall settings on Polycom.

I would like to go through main configurations on our Device first:

1. On system settings page, set up name and other basic properties.
2. Network Configuration:

Do not forget to put DNS servers in it, else your time server test will be failure. Default time server is

3. Other additional settings, such as snmp, multiple camera, multiple screen support, multipoint support. Some of them may need license to support it.

4. Since we are using Internal IP address, this device definitely is behind firewall or other security devices. During testing, we found we could not get video and audio but other site can see and hear us. After searched some documents and played a little bit, we found trick part is NAT configuration on HDX 8000.

6. Enable Remote Monitoring
By default, we could not see camera snapshot from remote website. There is no option you can enable it from GUI. 
Another trick is to do it from Physical Device by remote controller at meeting room. 
after enabled Video over the web, you will see near end video or you will see both near and far end in a call. Also you can control pan left, right, close, further etc.
