similar to: UDP behind a NAT

Hi, I read about the invitation protocol that will be introduced in 1.1pre8. Is there any mechanism of UDP hole punching to establish a VPN behind NAT?

Something tells me this was covered recently, but i didn't find it again in gmail. The nodes see each other but if i have something misconfigured that is decreasing my speed. All my nodes are behind NATs. i have a remote node that connects to a central node via port forwarding from public port 7777 to hp821 running on port 655. remoteNode ----> public ip 1.2.3.4:7777 ---->

Hi, I've followed the guide at: http://blogs.operationaldynamics.com/andrew/software/research/using-tinc-vpn and have a working tinc VPN. Here's my topology: - CentralNode has a fixed public IP address that everyone connects to - Leaf1 and Leaf2 may have different IP addresses depending on where they are, and usually those will be behind NAT (think, two laptops going around and you get

Hi all! I still have never managed to fully wrap my head around how UDP data tunnels can be established between nodes. Everytime I think I understand it, I see something that confuses me again Just now I am seeing the following: I have nodes A, B + C A has everybody's keys and host configuration files. B and C only have A's key, and host config with A's public IP address. B and

I can confirm that Steam In-Home Streaming does work properly over tinc, for having tried it myself, as long as tinc is configured to route the broadcasts properly, as Guus described. Note that it would be easier to set up tinc nodes on your Windows desktop and Linux laptops, to avoid the additional complication of having to relay broadcast packets between your local networks and the tinc network.

Hi, I have a tinc tunnel up and running. I connected 2 hosts with a net behind. Host A with static ip 1.2.3.4 with 192.168.1.0/24 Host B with dhcp connection with 192.168.2.0/24 the whole net is 192.168.0.0/16 I can reach at any time any host behind A from a host behind B. But I can reach a host behind B only, if traffic (keep alive like ping) from B goes continousliy from B to A. I am running

I would like to discuss the following commit: https://github.com/gsliepen/tinc/commit/4a0b9981513059755b9fd15b38fc198f46a0d6f2 ("Determine peer's reflexive address and port when exchanging keys") This is a great feature as it basically allows peers to do UDP Hole Punching (via MTU probes) even when both are having their source ports rewritten by a NAT, which is extremely useful.

Hello, We are using tinc 1.0.24 with switch mode. Some questions regarding to the UDP connections on tinc. As far as I understand tinc is building meta connections with "ConnectTo", and "ADD_EDGE" packet. With the help of EDGE info two nodes who don't have direct meta connection are able to communicate through direct UDP connection. I understand we can dump the meta

It seems if I use port 53, it works (This has both TCP and UDP open) However if I use 500 UDP (TCP is blocked) it doesn't work.

So i successfully upgraded my Debian vm''s to Debian 6 on XCP 1.0, but when i try to install a new clean one it always fails. Why is this? The VM won''t even start, while i used the Debian 6 squeeze template. Is this even possible?

Hi Guus, Unfortunately, I often notice that even with the advanced UDP hole punching mechanisms that tinc uses, I still come across cases on my network where two nodes behind NATs cannot talk to each other because one of the nodes is behind a "strict" NAT that won't use consistent source ports for UDP packets that are sent to different destination addresses. More formally, this

I have some tinc nodes behind a nat router. Which ipaddress should i use in de host file for the tinc nodes behind a nat router. The internet ipaddress or the private ipaddress ? Perry

At the moment I have 2 network connected in a VPN and I'm planning to extend this. Actual status: Network A has a public IP Network B is behind a provider-scale NAT. Actually I'm using openvpn with a single UDP connection from B to A, and hosts inside Network A can communicate with B. I tried with tinc, and I saw tinc has to go TCP-Only for accomplish this. This is because Tinc

Hi all, I am new to Tinc VPN and really would like to make full benefit of this implementation if possible. I would like to know whether I will be able to use Tinc to its full potential. My current setup is as follows, IPfire router/firewall(openvpn client) --->ISP(Internet)--->Amazon VPS(openvpn server). The ipfire router is behind a CARRIER-GRADE NAT, I am able to reach the network

Hi I'm trying to implement a scheme in which the nodes will have a direct UDP tunnel to each other. First, all nodes make connection with one public node, and then make connections with each other. And I came across the following problem: Remotely located nodes can establish a direct UDP connection, but the nodes that are in the same local network can not, and all traffic goes through the

Hi, I'm running some tinc clients behind a NAT (masquerading, Cisco Router) connecting to a host outside on a public IP in a different network. The tunnels get unstable every few minutes and I see packet loss when pinging the clients on their internal tunnel IPs from the host side. Before putting the tinc clients behind the NAT they were running on public IPs too (clients and host in
