Static IP Setup

Ok, I am not a huge techie, but need to set up a server behind a standard business class modem with a static IP. Here is my setup...Comcast cable modem with a netgear nighthawk AC1900 router behind it in passthrough mode. I have the server (WD Sentinel DX4000) hard wired to the router. I purchased a static IP from Comcast, but I don't know how to set up the server to use the static IP. Do I set it up under the modem settings? Or is it something I have to do under the router's settings? I already have the DNS access set up through our web host, and was able to previously access the server remotely via the web, but since I have purchased the static IP, the server is unreachable. Any help would be greatly appreciated! And if you could use simple terms I would be grateful! 🙂

typically, you would configure the WD box itself with the Comcast-provided static IP address, subnet mask, default gateway, and DNS servers, and then you would plug the WD directly into one of the 4 ethernet ports on the Comcast modem. Dont put the WD behind your router; that would only complicate things.

Thanks for the quick reply! I will try this setup out. I never thought about going directly to the modem with the server. I guess I didn't think about the firewall on the modem being the main security point. I will try connecting directly to the modem and see if that works.

As far as the server settings, I shouldn't have a problem setting the static IP on the server itself, I just may be back with questions on forwarding/routing through the modem to get to the correct ports. Thanks again!

Hello Sincerelyme2003 and welcome,

train_wreck is right on as usual.

However, also make sure that if your Server is not using any DHCP for any specific clients it is hosting. If it is, then you should consider disabling the Comcast modem internal LAN DHCP server to avoid any DHCP conflicts. This is typically done as good networking practice and will avoid any packet loss, trace route hop issues, etc. You can log into the Comcast modem as follows:

1. connect any computer ENet cable to any of the free Comcast modem lanPorts 1-4

2, bring up a browser and type in 10.1.10.1, enter

3, username=cusadmin,password=highspeed, then click LAN link

4. put your cursor on X radio box next to LAN DHCP Server and click the X to turn it off and this disabled the DHCP server after clicking apply button.

Hope this helps you out.
