I have a configuration where on my 20.04 server I've set up a network namespace called vpn in which there's only a loopback device and a tun0 device which is a openvpn connection to the internet. I've an application running in that namespace which wants to be administrated via a web UI from the LAN. For obvious reasons in my current configuration there's no way to access the UI from the LAN.
The current scenario of my interfaces with their IPs and Gateways are as follows.
IF11 192.168.1.100 GW 192.168.1.220
IF21 192.168.1.210 GW 192.168.1.1 IF22 192.168.1.220 GW 192.168.1.250
IF31 192.168.1.250 GW 192.168.1.1 IF32 x.x.x.x
The way I want my network traffic to move is as follows:

I want to create a VM VBOX Ubuntu to be a gateway in my home lan to route to my enterprise VPN. The problem is that my VPN when is stablished, create a route per route entry with metric 1 to be routed to the VPN. In this way local routing is disabled. If you modify or create a route, the VPN disconnects. I want to know if anybody see any solution, for instance using iptables.
I see in a tcpdump t ...
I want to use a VPN only for some specific routes (so that the default route is not on the VPN).
So in the Add VPN dialog I selected the "Use this connection only for resources on its network" (this doesn't change the default route) and then I added some subnetworks that I want to route to the VPN.
However, I'm not sure which gateway should I set here, as this is the VPN's gateway address, and it's ...
I am able to ssh from one host in Mexico to another in New Jersey, but when I start the ssh from the New Jersey host going to the same Mexico host, I get "no route to host". While troubleshooting with tcptraceroute I see that the last 2 ip addresses are duplicates; traceroute hits an infinite loop and stops.
I have 2 questions. What is the magic that allows packets to return from New Jersey to Me ...
I'm trying to connect between 3 Ubuntu 18.04 devices (1 Laptop + 2 NVIDIA Jetson Nano) where the 1st Nano acting as the gateway between the 2nd Nano and Laptop.
Currently the 1st Nano have
10.42.0.1 acting as a WiFi Hotspot (for the Laptop) and
10.42.1.1 Ethernet (for the 2nd Nano) and I can connect between:
[x] 1st Nano <-> Laptop
[x] 1st Nano <-> 2nd Nano
I have configured my VPS to listen to multiple IP addresses (whole subnet, 255 addresses), for example:
network: version: 2 renderer: networkd ethernets: ens3: addresses: - 184.108.40.206/32 - 220.127.116.11/32 - 18.104.22.168/32 - etc.
How can i make sure that the inbound address, for example
22.214.171.124 matches the outbound ip
126.96.36.199 ? When i connect to my serv ...
Would like this question (https://unix.stackexchange.com/questions/354854/how-do-i-create-centos-7-persistent-policy-based-routing-rules) answered for ubuntu using Network Manager, not CentOS.
Netplan documentation suggests this is possible with networkd (https://netplan.io/reference/#routing). However, I'm trying to modify routes for a cellular modem and networkd does not support cellular modems, Net ...
I'm replacing a CentOS server with an Ubuntu 20 one. I need to duplicate the older servers routing configuration. The outputs of
ip route show and
route are not directly usable as inputs.
I'm a bit reluctant to hand-translate the output into route commands, because errors always creep in. Is there a better way?
I have a lab setup with multiple pieces of equipment that can be controlled remotely using each one's respective embedded Telnet server. I can connect to each one easily by configuring a static IP for the lab computer and pointing the default gateway to the equipment IP. I have them all plugged into a network switch connected to the computer's Ethernet interface.
As is, I can only interface with ...
I'm a beginner ubuntu user. I've been searching the internet for months on how to do this and I literally even partially took an online course on networking and I still made no progress. I'm trying to configure a desktop with two ethernet ports as a VPN router. The setup I have in mind is this
WAN---> Modem ---> VPN Router ---> WAP & switch ---> LAN
I'm trying to make it so that

Hi . I needed to auto-connect my system to another system via Ethernet so I assigned both these systems respective static IPs. On my host system, I did this by editing the
auto eth0 iface eth0 inet static address 10.0.0.1 netmask 255.0.0.0 gateway 192.168.1.254

I use an industrial camera. I also have access to the modem. The problem is that if the Internet comes up first and then the program has access to the camera, then the camera gives an error and has no image. If the program has access to the camera first and the Internet comes up after a while, the camera does not have any error and gives frames correctly. How can I solve this routing problem?
