Problems with setting up a Static IP?

Question

I am trying to set up a Static IP address for a server. I have done this before, but had to reset my modem because I forgot the password for something (Not the password to get onto the router though, I was able to port forward). 
 So I have portforwarded everything, and as I am setting up the static IP address, I am in the Internet Protocol Version 4 (TCP/IPv4) properties and I tell it to use the following IP address. I put in my IP for the IP address, the Subnet mask automatically fills in, and the default gateway, which for me is 192.168.0.1. Then I go into the ipconfig/all in command prompt and type in the Preferred and Alternate DNS server IPs.

This is how I have it set up:

IP address: 192.168.0.150 
 Subnet mask: 255.255.255.0 
 Default Gateway: 192.168.0.1

Preferred DNS server: 72.240.13.7 
 Alternate DNS server:

I click Validate settings upon exit, and when I exit, I get a message;

"Warning - Multiple default gateways are intended to provide redundancy to a single network (such as an intranet or the Internet). They will not function properly when the gateways are on two separate, disjoint networks (such as one on your intranet and one on the Internet). Do you want to save this configuration?"

I have done this before with absolutely no problems, got it the first time I tried, but it all got reset, so I am trying it again, and I do not have multiple gateways, so I don't know why it is saying that.

Here is a screenshot:

I have no idea what that means, and never had this problem before. What am I doing wrong and how can I fix it? I have tried ignoring it, but it just disconnects me from the internet until I run a diagnostics on it.

At the bottom of the page where you entered your IP information there is an "Advanced" button.  Click that and check to see if there is another IP address or gateway defined in there that is maybe from an old configuration.

Assuming you are running Windows, which seems likely because of the ipconfig command you mention.

In the properties of the TCP/IPv4 item, there is space to define the primary and secondary DNS servers. You should define them in that section as you appear to be doing, and not using the ipconfig command.

It looks like you have two network adapters. Make sure the other adapter is not set up with static addresses on the same sub-net even if it is disconnected. Either set it with details for a different sub-net, or alternatively set it to use DHCP.

I hope this helps.

If you check the ip settings of your other adapters, you may find that they have a different default gateway set.  The warning you are getting (and that's just what it is, a warning, not an error) is telling you that you have multiple network connections with multiple gateways, and its asking you to be sure that's what you want.  As long as you are sure that you used the correct settings for this adapter, the warning can be safely ignored.
