If you are setting up a new default route for a vpn, does the ip you are connecting to become the default route?
Maybe its the gateway of the ip address at which you are connecting to?
After some research, it appears the virtual private tunnel's entire sub-net is the new gateway after connecting to the vpn.

I am struggeling to connect to my home server that is connected via a Fritzbox router to the internet. I want to connect to the home server from outside of the home net, as it serves as a NAS and provides HTTP(S) services.
The problem is, that I don't understand how to connect to the server over the internet. My Fritzbox is connected to my internet provider via DS-Lite internet connection. As far as I understood, this means that my Fritzbox has no public IPv4 address and therefore the server is not reachable.
Is it still somehow possible to connect to the server?
Reading your question, I can see that there are multiple steps to solve this.
figure out if your internet provider allows you to have incoming connections
I do not know, what a ds lite connection is. Depending on your connection type, e.g. glass fibre, dsl, mobile and your provider incoming connections might be allowed or not. Also specific ports might be forbidden.
Enable port forwarding for incoming connections to your lan server.
Your fritzbox does not know, where to route the incoming connection to.
Make your lan server ip address static. Go to your fritzbox admin page and create a port forwarding rule and map data incoming on port 80(HTTP) and 443(HTTPS) to the lan server ip address.

Figure out the fritzbox's public ip address by checking out this website from within your lan. https://whatismyipaddress.com/
Connect to your server via http(s)://publicip
setup dynamic dns to have a public domain, which you can use instead of the ip address.
Usually private customer internet connections use dynamic ip addresses. So your ip address changes regularly. This is annoying, because you need to lookup the ip address before you can connect again. To avoid this issue, you can use a dynamic dns provider to give you a domain name, which you can use instead of the public ip address. Your fritzbox should have this kind of functionality already. If not, you can also configure it on your server with a cron job.

This provider is easy to use and for free: https://freedns.afraid.org/
use the dynamic dns domain name instead othe public to access your server from anywhere
Be aware, that having open connections to your local network gives attack surface from the public internet. So people might steal or delete data on your server or abuse it in other ways.
I am using (airtel xstream fiber) connection and trying to do port forwarding. I forwarded port 3000 of wan and direct it to my system ip address 192.168.1.2 on port 3001.
Node server is running on my system on port 3001. And I can access my hello world website locally using 192.168.1.2:3001. But when I am trying to access using public ip, it show this error code "ERR_CONNECTION_TIMED_OUT".
Also, I found my router port 3001 is open using online port checking tool/website.
So, Can anyone please tell what could be reason behind this ? Is this the problem with windows.
You first need to check what ports are open by your ISP. If your ISP is giving you a local ip at the router. Basically, creating a ppp connection. It may be using a cg nat. In that case you need to buy a static ip, without that none of the traffic will be Directed to your router. Let me know if you find something, I'm currently looking to get xstream airtel as well.
No there is no need for static IP to be access server remotely. As of now, What I see is airtel allocates new ip every 24 hr or when router got disconnected. To access your server remotely you can do two things. First one is more secured.
Change Primary IP adress of your airtel router and use Portforwarding so that its port 80 will be free for you.
Enable DMZ and point it to your local server IP. [192.168.X.X]. In this case all of your ports of the device are exposed to internet. If you want to be secure. Make sure add another router between server and airtel router and enable port forwarding.
But in this case there is a catch, When you try to access your local website using public ip (which you can see on google search) it will redirect you to airtel router panel. But when you try to access it using other device (not server otherwise server will get disconnected) connected to internet using other network(other that your current airtel router like JIO sim, Airtel Sim, etc), It will work excellently.
To get rid of dynamic ip use no-ip services. Its website will help you more. Basically, It is dynamic dns server where you will get free domain. That will get update regularly while its service running on your system. To use other dns provider service like godaddy you must need an static ip.
I have a machine in my private network with IP 192.168.1.10
I have a DNS name, "toto.mydns.com", a DNS client is running on the machine.
I configured the router for Port forwarding.
I can access the machine when i am outside my home, when using a pulic IP address it works but when i am at home and i get a dynamic IP address trough DHCP from my router, i cannot use toto.mydns.com anymore, i must use 192.168.1.10 to access.
I would like to know if i need to configure something on the router for that ?
Thank you !
toto.mydns.com will resolve to your external public IP
There will almost certainly be nothing routing that IP through to your router, and thus through NAT to your internal address.
The easiest way to resolve this (Pun very much intended) is to have a hosts file entry on your computers running inside your network so that they resolve the same DNS address to the internal address.
A much harder, but more fun, way would be to set up your own DNS server inside your network, have the DHCP dish it out as the primary DNS server for your network and put in an entry for your internal address :D
Have fun...
Toto.mydns.com is accessible from outside,this DNS is assigned on a machine with a static IP address(sorry not dynamic),so the IP of this machine is 192.168.1.10.
Whrn i am at home in my private network i need to enter 192.168.1.10 and toto.mydns.com does not work.Any help???
The IP of of an instance created through Openstack is 10.0.0.2. But when I tried to ping this IP from other machine, it was not successful, however I am able to ping this IP from the machine on which Openstack(Devstack) is installed.
What could be the reason and how to resolved this?
This may help you: http://www.liquidstate.net/blog/technology/openstack-havana-home-lab-on-centos6-with-external-networking/
Basically, you need a virtual router to connect from you LAN to OpenStack private network.
I think, you don't need a Floating IP exactly on each instance. Only a virtual router, then you can create a static route on each machine in you LAN, for example:
ip route add 10.0.0.0/8 via 192.168.1.100 dev em1
Good Luck!
This IP is a private one, by default, when you deploy a new instance it is deployed with a private IP.
If you want to have a public IP, you need to create a floating IP for your project and afterward, you should assign one IP from this pool to the server instance that you have created previously.
After that you could access to your server instance without any problem.
I hope that it could help you.
Default Gateway is used when the host doesn't have any route information for a particular packet. So it will ask the default gateway.
Now for a router there will be lot of static routing information, but if the router is not able to find a routing information, it should take the route mentioned in 0.0.0.0 (which is called default route). Now is this called Default Gateway of a router?
I read few documentation, but i wasn't able to find an accurate definition for Default Gateway wrt router.
It is possible to have a default gateway (typically noted as a route to 0.0.0.0) for a router. It's also known as the "default route".
A typical case for this is where a router has an upstream ISP that it's using for transit to "the rest of the Internet". In this case, the route for 0.0.0.0 would be set to the IP address of the ISP side of your link to the Internet
For example, in the most basic case on a cisco router, if your side of the ISP link is 1.1.1.1 and the "far side" of the ISP link is 1.1.1.2 you'll use something like:
ip route 0.0.0.0 0.0.0.0 1.1.1.2
...to route traffic that doesn't match any other explicit routes in the routing table, out the ISP's interface. The active connection to your ISP installs a route in your routing table, so you know how to get to 1.1.1.2. So if you're trying to get to an external address (say 10.20.30.40), your router is effectively doing two lookups: first it looks up 10.20.30.40 and sees that it should use the default route, which points to 1.1.1.2. It then sees the connected route for 1.1.1.0\30 in the routing table (which contains 1.1.1.2), and then uses that to route the packet.
The default gateway used on on most routers, for the LAN, will be the private IP of the router itself, ex:
IP Address 192.168.5.100
Subnet Mask 255.255.255.0
Gateway 192.168.5.100
Local DNS 192.168.5.100
The default gateway assigned to the WAN port will be assigned by the ISP provider, if the public interface is connected to such. If not connected, you will probably see 0.0.0.0 assigned to the Gateway and other public ip settings.
yes it has, go to command prompt, type ipconfig/all for windows and for mac https://www.expressvpn.com/support/troubleshooting/find-default-gateway/
you can see the default gateway. in accessing it on browser, type https:// and the ip of your router
It's just a simple task:
Open your network and sharing center.
Click on "change adapter setting on your top right"
Right click on the ethernet adapter
Click on properties
Choose configuration
At your right in thee dialog box, there's an option "Enable". Change it to "Disable"
All done now ... Type 192.168.1.1 in your browser
Voila... It works!
