What gateway address should i use

Most often it is a router or a firewall with routing setup on it. At home, my default gateways are on the firewall which could be called a router as well although the router itself i.

A router is something that routes packets. I think this part of your question is the problem. I was under the assumption that whatever device which was doing the routing DHCP was the router? I was told by multiple people including "Eli the Computer Guy" this was how it should be setup. In a larger environment, I like to separate out the overall routing from the WAN providers devices.

I've found it's particularly useful when you may be transitioning from one service to another. So something like the internal default gateway is If you transition to a new WAN service, park it at If you want to be able to communicate outside of your given subnet then, yes, the default gateway has to be set to a device or system that has routing capabilities. However, technically speaking, the default gateway isn't necessarily the only router you can have defined for use, it's merely the router to be used if no other route has been statically defined to use a different router.

Even though Windows doesn't readily allow for it in their networking interface, you can actually specify different routers to be used to route to different subnets. Having a statically defined router for a different subnet could be used as a means of controlling which systems had access to certain resources so long as the default gateway that is used was not set up to route traffic to or from that subnet.

While a DCHP server can provide a computer with a default gateway to use it is not involved in routing whatsoever. Similarly, a router can be set up to forward DHCP requests to a server on a separate subnet but that does not mean that the router has any role in providing a client system with an IP address. DHCP just gives out addresses.

Routing actually delivers stuff. This is similar to DHCP. Routing is more like your postal service. In this example your local post office would be the router, as it accepts and redirects parcels going to addresses assigned by the municipality. Both roles are done by the same device in consumer-grade routers, and most commercial routers can do this as well, but they don't have to.

Default gateway is simply whatever device is doing routing for the network you are on. If you are using VLANs, you might have a layer-3 switch doing routing in which case that would be your default gateway. DHCP cannot do routing. To do routing you need a layer 3 device. DHCP is a protocol and it's at layer 2. It is the default gateway device that decides where to send the data. This is an important point - with my setup, the firewall is where the default gateways live.

Almost all the routing is done there. In turn it has a default router which is the internet router. In this context L3 , a route is an IP address to which traffic is sent for a destination IP that is off the local L2 network. The route must point to an address that is on the same L2 network as the originating host. This is because the host communicates with a gateway at L2. The subnet mask number helps to define the relationship between the host computers, routers, switches, etc.

The IP protocol is installed by default on most operating systems. In the first selection box, click on the down arrow and select the proper network interface. There will be a network connection listed for a dial-up, and one listed for each network card installed in the computer. DNS Suffix. Connection-specific DNS Suffix. The IP address will be listed in the current command line window. Other information such as the gateway address and DNS numbers will also be displayed.

This window will contain information such as IP address, subnet mask, router address gateway , name server address DNS and other IP information. If the network settings are grayed out select the click the lock to make changes button.

Then enter in the admin account name and password to proceed with viewing the network settings. Choose the ethernet port by clicking the double arrows next to Show Fields and select Built in Ethernet.

The IP address, subnet mask, router gateway and domain name servers DNS will be displayed in the active window. The last two lines of the information displayed on the screen will be the IP address and the subnet. Post by alexandervj » Fri Jan 24, pm. Post by nigerag » Sat Jan 25, am.
