The default route in Internet Protocol Version 4 (IPv4) is designated as the zero-address 0.0.0.0/0 in CIDR notation, 1 often called the quad-zero route. The subnet mask is given as /0, which effectively specifies all networks, and is the shortest match possible. A route lookup that does not match any other route, falls back to this route.
Default gateway set to 0.0.0.0. I was recently trying to troubleshoot an IP network issue. I had given the Ethernet port on my Laptop (Win 10 Pro) the IP address of the kit that had problems communicating. Gateway is 0.0.0.0, (zero network or (0.0.0.0) which in Internet Protocol standards stands for this network, i.e., the local network). The interface is X0, the LAN of your firewall (It’s aimed at X0 so that broadcasts should stick within that interface). Metric is 20, which is the default for a locally attached network. The default route in Internet Protocol Version 4 (IPv4) is designated as the zero-address 0.0.0.0/0 in CIDR notation, 1 often called the quad-zero route.

Jul 16, 2010 · Each network host has a default route for each network card. This will create a 0.0.0.0 route for such card. The address 0.0.0.0 generally means “any address”. If a packet destination doesn’t match an individual address in the table, it must match a 0.0.0.0 gateway address. Mar 17, 2020 · Click Network, choose the network connection you're using, then click Advanced. Click the TCP/IP tab and locate the IP address next to Router. Another way to find your Mac's default gateway is to use the netstat command. Open a terminal, enter netstat -nr | grep default, then press the Enter key. Jul 04, 2017 · route delete 0.0.0.0 ipconfig /release ipconfig /renew Note: If you have Bonjour installed, then it's possible that's what caused the gateway to be 0.0.0.0 and it could do it again. You might want to set it to Manual Start in Services and Disable it in Startup (if it's there)
It is tradition and habit for network engineers also configure a static default route (e.g. 0.0.0.0/0, ::/0) toward the firewall on the router internal to the firewall. As shown in the below
IP Default-Gateway vs IP Route 0.0.0.0 on layer 3 switch Correct, you use ip default-gateway if the switch is layer-2 and you just want connectivity to the rest of the network for management. ip route is usually used when the switch is utilized as layer-2 and layer-3 (router). Here is good doc explaining the difference: Jul 01, 2011 · Windows 7 x64 pro/ Windows 7 x86 Pro/ XP SP3 x86. 5,056 posts. I believe the 0.0.0.0 default gateway can be caused by the infamous bonjour services, and also sometimes by ipv6. Default Gateway . . . . . . . . . : 0.0.0.0, 192.168.1.1. So that 0.0.0.0 gets set as your default gateway and your real gateway address gets set as a secondary gateway. Your internet connection can NEVER work this way, as all WAN IP's will try to route through that 0.0.0.0 gateway, which is invalid.
pi@raspberry:~ $ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.0.30.0 0.0.0.0 255.255.255.0 U 202 0 0 eth0 If I run sudo dhclient or route add default gw 10.0.30.1 the default route is added and I can hit WAN no problem. But every time I restart the pi it loses this setting.
Where 192.168.0.1 is my local router through which I'm connected to the internet, 192.168.0.11 is my client computer's address on this local network, 86.129.242.71 is my VPN server, 10.1.0.1 - 10.1.0.10 is my IP range for VPN clients and 10.1.0.1 is the default gateway on that server. Recently, and randomly, the default gateway on my Arris modem changed from 192.168.0.1 to fe80::201:5cff:fe75:5e46%7. At the same time, the switch that i have connected to my modem stopped working correctly - It will only allow 4 ports to be active at any time (i am using 8 of the 16 ports for various LAN connections, google wifi, and ooma telo). pi@raspberry:~ $ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.0.30.0 0.0.0.0 255.255.255.0 U 202 0 0 eth0 If I run sudo dhclient or route add default gw 10.0.30.1 the default route is added and I can hit WAN no problem.

I then went to go edit my IP address settings from my xbox and it shows my IP address which is correct, subnet mask, and a gateway with '0.0.0.0' What am I doing wrong? edit: Yea, I know how to do that but the Default Gateway didn't show there either
