It only takes a minute to sign up. I have setup a router with OpenWRT I configured OpenVPN client software to connect to vpn service vpnservice1. In the OpenWRT system logs I can see that the openvpn client successfully connects to vpnservice1 and interface tun0 is opened. My aim is to route all traffic from network wi-fi-1 I would still like devices connected to the wi-fi-2 network With the configuration I currently have - devices on the wi-fi-1 network can connect to the internet via the default gateway.
However devices connected to wi-fi-2 cannot connect to the internet. Any assistance is welcome :. After restarting the VPN session the syslog entries indicated the vpn session connected successfully. However the wi-fi network isn't connecting to the internet over the vpn.

I just started using it, so I guess I can only give some hints and no working solution for your specific case. With iproute2 you can implement policy routing conditional routing. In your case you need two different routes for your two devices br-lan and br-vpn. For br-lan this seems to be already in place. Now you need to route all traffic from br-vpn or the subnet it represents through your tun0 device and the vpn. My guess would be something like this probably not working but hopefully gets you going in the right direction :.
Intuition: you add a rule for all traffic coming from your Then you add a default rule in your admin table, routing everything by default through your vpn. I'm a bit confused by your configuration.

In this example, the ip-address of the system where the route command is being executed is The above command shows that if the destination is within the network range In order to send packets to destination which is not within this ip range, the packets will be forwarded to a default gateway, which decides further routing for that packet.
We will see this shortly. By default route command displays the host name in its output. We can request it to display the numerical IP address using -n option as shown below. We can specify that the packets that are not within the network has to be forwarded to a Gateway address.
Now we have just added a default gateway to our machine. To verify whether it is working properly, ping some external host for example, google. The above 2 examples would have given a good idea about how routing is done within a network.
Now we will see other command line options available with route command. Kernel maintains the routing cache information to route the packets faster. To do that, add the following entry. However we can still access other hosts in the network for example. If you want to reject an entire network In the diagram below, we have 2 individual networks Now we need to add a routing entry such that we are able to ping Now all the packets addressed to Now we need to access the internet from these 2 different networks.
For that, we can add a default routing when no routing rule matches to the Well written. Thanks for this tuto, and for the comments about iproute2, i need to learn this one too apparently. A reminder that adding these static routes does not make them persistent across system reboots. Make sure to commit these changes to the relevant files within your distribution to make these persistent. Thanks Assi, nice tip!
Maybe your distro does not have the package installed. In step 7, where do we add the default route? Hi I dont understand this part : ——— 4. It then checks whether the destination is within 2. IN this example, it is not ——— why it should check fore 2. I think this the thing from which I had a routing fobia.
Which is now vanished. Thanks for explaining step by step which helps beginners alot.Top 10 Linux Job Interview Questions
How do i undo the block? In steps 5 and 6, why are routes being added on the Gateway to the local subnets. Is that necessary?
Hi, really great work, i was trying to implement the sample network using VMs in Openstack, but can seem to ping the networks from each other, though they can both ping the VM which i was using as the gateway, any help on what might be the reason i can implement it in an all VM situation. Thanks a lot though i used route often but was filled up with some doubt.Static IPv4 routes can be defined on specific interfaces using route sections.
As for aliasesmultiple sections can be attached to an interface. To disable a route quickly, the option enabled is not available.
It seems that on openwrt Like the lan has the gateway Could be added through ip route commands tough. IPv6 routes can be specified as well by defining one or more route6 sections. User Tools Register Log In. Site Tools Search. Sidebar Welcome to the OpenWrt Project. Supported Devices.

In some specific types of environments, you might find it useful to add a static route to the routing table in Windows. A routing table dictates where all packets go when they leave a system—whether that system is a physical router or a PC.
Most routers—including the one built into your Windows PC—use some form of dynamic routing, where the router is capable of selecting the best place to forward packets based on information it gets from other routers.
If any of those apply to you, read on. Before you get started adding routes, it may be helpful to view the routing table first. You can do pretty much everything in PowerShell that you can do in Command Prompt, plus a lot of other useful things.
The metric cost value is just a cost that is relative to other costs in the table and is used when Windows decides between multiple routes that could reach the same destination. So, for example, if you wanted to add a route specifying that all traffic bound for the When you add a static route, by default it only lasts until the next time you start Windows.
The reason for this is that many companies use a coordinated list of static routes that gets updated fairly often. Rather than adding and updating all those routes on every machine, they just distribute a batch script file that adds the newest routes during Windows startup. This keeps the routing table relatively uncluttered.
You could certainly use the batch script method yourself. A persistent route stays in place even when Windows starts up.
Using the same command we used earlier, you could make that route persistent with the following modification:. Of course, there will come a time you might want to remove a static route from your table. All you have to do is type a command using the following syntax:. So, to delete the route we created earlier with the destination network Yes, using static routes is a bit esoteric when it comes to managing most home and small business networks.
