Hello Rahul
iamrahulus1. Why it cannot be configured with DHCP service (With my modem router connecting to internet as the provider).
It sounds like the DRAC is having a difficult time saving the DHCP information. I would recommend resetting the DRAC to default and attempting again. I would recommend against using a DHCP address since you need to know the IP address to the DRAC to be able to connect. If you configure it for DHCP then it could change.
iamrahulus2. How is it possible (Without having a static address for its NIC) to get the public IP address of its NIC?
3. How to set it up with my DynDNS account?
This functionality has nothing to do with the DRAC. This has to do with your personal network, and an understanding of how networks operate.
To accomplish what you are wanting to do then I would suggest using port forwarding on your switch/router. Here is an example of a way to configure it:
- Find out what your public IP address is. You probably only have one public IP address. This is not something you program into the DRAC. I would recommend going to http://www.ipchicken.com/ It will list your external/public IP address. I will use 72.1.1.1 as an example.
- Make up a port, it does not have to be anything specific, but it should be a port that is not used by anything else. I will use port 4444 in this example. After you find out your public IP and make up a port then register that with dyndns. It will look like this 72.1.1.1:4444
- After you have registered the DNS name with that IP address then when you type in that DNS name to a browser address it will direct you to the associated IP address(72.1.1.1:4444)
- The next step is to forward that port to your DRACs IP address. To do that log into your router. Every router is different so you will have to refer to your routers documentation on how to configure port forwarding. Forward port 4444 to the IP address of the DRAC(e.g. 192.168.100.1).
After you set all of that up you should be able to type in DYNDNSADDRESS to your web browser and be routed to your DRAC. Most internet service providers block inbound web traffic and some secure traffic. You will likely need to be on a business line with unrestricted transmission to perform this since the DRAC passes encrypted traffic and several types of traffic.
This is well outside the scope of support the DRAC was designed for, so I'm not sure if it will work. I have not tested this.
Thanks
