Packets from one VPC that have a destination of a subnet in another VPC, for example from 10.1.0.0 to 10.2.0.0, route through the transit gateway, where they are blocked because there is no route for them in the transit gateway route table.

As a Gateway. When 0.0.0.0 is specified as the Gateway, it means: read the line with 0.0.0.0 as the destination and route the packet through this interface. But when you have a second network interface or more, you can have the IP of one of those network interfaces specified as the Gateway instead of 0.0.0.0, and packets will be routed through "IP Route 0.0.0.0" is usually used on devices that are L3 eg Layer 3 switches/routers etc: Related terms Layer 2,IP management: AD, floating default Route: General Usage: The default gateway on the switch is for management purposes only: IP Route 0.0.0.0 is used as another way to set the gateway of last resort on a router. Transitive traffic Destination 0.0.0.0 Netmask 0.0.0.0 Gateway 0.0.0.0 and Destination 0.0.0.0 Netmask 0.0.0.0 Gateway aaa.bbb.ccc.244 Checking through control panel only indicated one default gateway aaa.bbb.ccc.244. I did a "route -f" and the 0.0.0.0 gateway entry disappeared, as did the network problems I was trying to troubleshoot. When connecting from the remote computer, I get an IP address from the dhcp pool but the default gateway is 0.0.0.0 and i cannot ping the remote server or asa. Also I cannot get webpages once connected to the VPN as the routing is through 0.0.0.0 I am using Shrewsoft VPN client due to a 64 bit machine. The "ip default-gateway " is used when routing is disabled. The "ip route 0.0.0.0 0.0.0.0 " is for when routing is enabled. If routing is enabled on the switch, it will ignore the "ip default-gateway" command in favor of the ip route command. HTH, John *** Please rate all useful posts *** Hi, We have setup a windows 7 machine, it takes IP address properly from DHCP server, but takes two default gateways . First default gateway - 0.0.0.0 & second default Gateway 192.168.1.1 (This is correct one). Unless I delete the first default gateway manually my machine does come on the · Just found a solution to my problem. The problem was Gateway with 0.0.0.0 means this route rule do not need a gateway, you pc might connect to other device by a switch/bridge. Reply. NetLover says: February 22, 2016 at 9:05 pm . 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

Destination 0.0.0.0 Netmask 0.0.0.0 Gateway 0.0.0.0 and Destination 0.0.0.0 Netmask 0.0.0.0 Gateway aaa.bbb.ccc.244 Checking through control panel only indicated one default gateway aaa.bbb.ccc.244.

I have setup a Network Connect policy for some remote users, using a SA2000. I have noticed that when they connect their default gateway on the Juniper Network Connect Virtual Adapter gets set to 0.0.0.0 On a different SA2000 when people use network connect the default gateway gets set to the same I 0.0.0.0/0 means, effectively, all-wild-card. So traffic going anywhere is re-directed to the Internet Gateway. Which is exactly what you want to access the internet :) Be aware, on a security group, a 0.0.0.0/0 rule on the INCOMING traffic means anyone anywhere can connect via the specified port. What you are missing is a route to 192.168.1./24. When you try to connect to that subnet, it goes out your default gateway (local internet connection) since there is no specific route for it. Without using split tunnel, it works, because your default gateway is the remote server, and it knows how to get to 192.168.1./24.

If your virtual network is connected to an Azure VPN gateway, don't associate a route table to the gateway subnet that includes a route with a destination of 0.0.0.0/0. Doing so can prevent the gateway from functioning properly. For more information about using 0.0.0.0/0 in a route, see Virtual network traffic routing. Associate a route table

In your subnet route table, you can specify a route for the internet gateway to all destinations not explicitly known to the route table (0.0.0.0/0 for IPv4 or ::/0 for IPv6).Alternatively, you can scope the route to a narrower range of IP addresses; for example, the public IPv4 addresses of your company's public endpoints outside of AWS, or the Elastic IP addresses of other Amazon EC2 IP Route 0.0.0.0 0.0.0.0 Creating a static route to the network 0.0.0.0 0.0.0.0 is another way to set the gateway of last resort on a router. As with the ip default-network command, using the static route to 0.0.0.0 is not dependent on any routing protocols. 0.0.0.0 is an IP address, but not a normal one. Devices assigned 0.0.0.0 are not connected to a TCP/IP network and might have experienced a failure. My fix removes the 0.0.0.0 as a gateway, and then renew's the IP address so that your real gateway gets set as the default one. When this bug happens, simply renewing the IP or even rebooting won't fix it. The 0.0.0.0 gateway gets saved and reloaded on reboot. By manually deleting it using the route command, it won't come back. If your virtual network is connected to an Azure VPN gateway, don't associate a route table to the gateway subnet that includes a route with a destination of 0.0.0.0/0. Doing so can prevent the gateway from functioning properly. For more information about using 0.0.0.0/0 in a route, see Virtual network traffic routing. Associate a route table In the Destination field, select Subnet, and leave the destination IP address and subnet mask as 0.0.0.0/0.0.0.0. In the Interface field, select the SD-WAN interface from the dropdown list. Ensure that Status is set to Enable. If you previously removed or redirected existing references in routes to interfaces that you wanted to add as SD-WAN
