Hello,I have 6 Ubuntu 18.04 machines in a Tinc (1.35) network, where 3 are in Spain and 3 in UK.One machine in each country is running Tinc, and as both ends are behind NAT, they both connect outward to an Upcloud VM. The 4 non-tinc machines can Ping and SSH each other without issue, and so from that point of view, the Tinc VPN is working fine.However, the 2 tinc machines can only ping and ssh

Hi, I'm trying a VPN via ssh between Linux (Suse 10.3, 5.0) and OpenBSD (4.2, 4.7). But it doesn't work...

Hi, Thank you Guus, I think the /16 solution is the easier to apply so I modified my tinc-up in host A to be like #!/bin/sh ifconfig $INTERFACE 192.168.10.1 netmask 255.255.0.0 a route -a from HOST A shows: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 178.62.128.1 0.0.0.0 UG 0 0 0 eth0 10.129.0.0

I have a 4 Node Tinc VPN setup with 2 nodes on my LAN and the other 2 outside the LAN in the cloud. Everything has been working great for about 5 years now, until today when I decided to move one of the nodes to another box. I basically, copied over the /etc/tinc folder to the new server and also moved the /etc/network/interfaces file, so that the new server was an exact mirror (more or less).

Hello all, I have a linux router with 2 interfaces(eth0 - ISP and eth1 - LAN). I''ve established a VPN connection(openvpn) over eth0 with a friend of mine => tun0 interface. I want half of my LAN to have Internet access through the eth0 interface and the other half through the tun0 interface. I''ve set up a script like the "load balancing split access" instructions

All, With the dual-ISP support in the latest versions of Shorewall, is it also possible to setup dual-VPN with something like OpenVPN? If so, what are the high levels steps that would need to be completed? Aaron

Hi, I am trying to access devices (ip cams) through clients using the tinc vpn. Let's demonstrate the problem with two clients: client name [ip in eth0] [ip in tun0] gl752 (A) 192.168.1.33 10.0.0.1 xps13 (B) 192.168.1.55 10.0.0.2 I also have an ip camera connected to the local network at 192.168.1.21. I want to try a situation where I am accessing, from linux box

Hello Lars, Thanks for your feedback. Unfortunately I made an error in writing the network I expected to connect to. I meant 10.3.0.0/24 The one I wrote in fact was one network of the already established VPN. I have included full details of my relevant files below. Background: I am trying to set up a second VPN between two servers: gtdb and db2. Both servers are already part of separate

Hi, after trying for days I ended up with a working tinc configurazion of 2 subnets, now my goal is to add 2 more subnets and comunicate. I might seem dumb at this point but honestly I don't work in IT or Networking stuff, and so I dont have that deep knowledge. A little explanation of my configuration is HOST A (VPN server) Public IP: 1.2.3.4 tun0 Subnet = 192.168.10.0/24 tun0 IP =

Keith, Thanks for the reply and the pointers. > Did you remember to activate kernel ip forwarding? > i.e. echo 1 > /proc/sys/net/ipv4/ip_forward ? I actually forgot to do this, but I have enabled it now in /etc/systctl.conf and can confirm now after a reboot that it's enabled. Unfortunately, still can't ping the node on the LAN. > and when I saw that I was about to cancel

Hi Parke, Thanks, no I had not run those commands, but after doing so, my VPN address is not visible. See below: nsasia at db2:/etc/tinc$ sudo systemctl enable tinc at VPN1 Created symlink /etc/systemd/system/tinc.service.wants/tinc at VPN1.service → /lib/ systemd/system/tinc at .service. nsasia at db2:/etc/tinc$ systemctl start tinc at VPN1 ==== AUTHENTICATING FOR

Hello Tinc list! I'm trying to set up a Tinc VPN between two KVM host machines so that a VM on one host can communicate with a VM on the other host. While I do have a good bit of experience with virtualization, I'm not a particularly savvy network guy, so this is proving to be a pretty big challenge. Requirements: * ALL VM network traffic must be secure. * VMs on one host must be

Guus, Thank you for your help (a)>>You said:- First, if you are already using "ip" to assign an address..... Why should I use "ip route" instead of "route add..." Surely both write same to the Routing table? (b) My problem was, that Tinc servers could not ping remote clients, whereas clients could ping successfully across VPNWhen pinging Client to Client

hey friends, I have installed OpenVPN 2.0.7 (i386-redhat-linux-gnu [SSL] [LZO] [EPOLL] built on Apr 29 2006) on Centos4.0 through rpm (diag repository). The network scenario of my office is below Remote Client ----> Internet <-------> Cisco Pix Firewall (Gateway) <----> VPN Server & LAN Clients

Thank you, Parke and Guus. I have now understood and got it working. Because of my beginner belief, I assumed that the tinc vpn end points needed to be on the same network. I have now discovered that the tinc vpn IP end points addresses can be arbitrary, and different! So I have set the end points to be local to the LAN they connect, and added on each tinc server a dev route to ensure
