Windows 7: Can I Setup Static IP Address Before Doing Port Forwarding On Router?

Can I Setup Static IP Address Before Doing Port Forwarding On Router?

Hello. I have a question to ask you.

Can a user setup a static IP address before doing a port forwarding on a router when your ISP (a big cable company) uses and assigns me a dynamic IP address? I wish to have port forwarding for a VoIP telephone on my router. The router I am wishing to port forward is a Netgear WNR2000v2.

I always thought when your ISP uses dynamic IP address, you cannot setup anything with your home networking with a static IP address. Am I wrong? Please explain.

Please reply.

Thank you!

The info that follows is not precise so that it can be concise.

For the purposes of this discussion, there are two sets of addresses:
Private and Public.

Your ISP assigns a public IP address to the public side of your router.
(85.12.xx.xx)

Your router assigns a private IP address to devices (computers/phones) in your home.
(192.168.xx.xx)

You can assign a static IP address to your phone or most any device on the private side of the router.

The public IP address that your ISP assigns to the public side of your router won't change very often - but when it does change - there are services that can track the change. And/or there are tools that will e-mail you each changed public IP address.


I'm not endorsing or suggesting that you use this service:
Managed DNS and Dynamic DNS - 100% DNS Uptime No-IP
The link is just the first example that I could find.


I would not download from this website:
Email My IP Free Download
The link is just the first example that I could find.

@ UsernameIssues & anyone else:

Hello. Nice to meet you. Thank you for your reply.

I see. So let me ask you this. Anytime the public IP address changes on the public side of the router, will this or will this not have an impact or effect on the private IP address (192.18.xx.xx) side of the router? Why I ask if the private side is *always* 192.168.xx.xx on my home networking side, specifically something like 192.168.1.1, 192.168.1.2, 192.168.1.3, etc. for each piece of networking hardware on my private side to my understanding; then why would any ISP IP address changes to the public side of router be any issue at all? What I am saying there would be NOTHING I WOULD *EVER* NEED TO DO to my *private* side of my router REGARDLESS when my public IP address is changed from my ISP. This makes sense to me. Am I correct? Please explain.

It just makes sense to me that anytime my ISP changes my public IP address every so often from their side or end, there is NOTHING I *EVER* NEED TO DO from my private side of the router?

I am kinda new to networking (novice), but I am learning quickly. :-)

Please reply.

Thank you!

Changes to the public IP will not change the static IP addresses assigned t devices on the private side of the router.

But here is the thing:
Some people like to be able to connect (via the internet) to devices inside their home while they are away from home. To do that, they need to know the pubic IP address or use a service that tracks that public IP address for them. For some reason, I thought that this was what you were wanting to do. If all that you need is a static/private IP address and port forwarding, then you don't need a service or a tool that keeps you informed about your public side IP address.

@ UsernamesIssues:

Hello again.
Okay, so public and private sides of the router do not interfere with each other. Wonderful to know that!!!

Yes, I learned something from you. Yes, I have heard about this advanced technology, but I did know how it worked and sharing a piece of it with me. All I need is simple static/private IP address and port forwarding. Like I said I am a novice and this is enough to learn and do at the moment to get this to work. Thanks for sharing a piece of advanced technology with me. Something I will have to look into in the near future - I'm curious about it.

Again, thank you very much!

Have a Happy Thanksgiving!
