I have got my ASTCC up and working , but facing a hard time understanding the terms in ASTCC what actually they are meant for. 1. What is Trunk in ASTCC and what are the meaning of the parameters such as Technology & Peer/Trunk ? 2. In the routes if I use 0 connect fee that means the user won't be charged for 0 sec calls right ? Inc. Seconds refer to interval ? If I set 500 in cost per

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

Ah! I'm noticing that configuring static ports on the NAT in front of a tinc node with a public IP seems to make a difference to the number of other tinc nodes that can then establish dire...

...allel, it will send UDP "probe" packets to the destination node. These probes serve three purposes at the same time: (1) they enable tinc to determine if the destination node is reachable over UDP; (2) if it is, they enable tinc to determine the PMTU; and (3) they de facto act as NAT hole punchers (because both nodes will be sending probes to each over at the same time using the same ports). - If the UDP probes do come back, indicating that the node is directly reachable over UDP, tinc will stop sending actual data packets through the "safe route" and will start sending UDP packet...

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
