after i ran "go get -u -v github.com/kanocz/lcvpn" under $GOPATH,
it shows:

how to fix the errors?

Ciao Kanocz,
you thought about porting it to freebsd/macos ?

Thanks.

Hi,

I have a scene that i need solve with VPN. My home raspberry need connect to my VPN on amazon and my customers need connect their pc/ios/android devices to that same VPN on amazon to access to raspberry.

How i can do it with this tool?

Thanks.

Hey,

can two servers connect to each other, if server 1 can contact server 2 but not the other way around due to firewall restrictions / missing port forwarding?

As Server 1 connects to Server 2, Server 2 should not need to connect to Server 1 anymore right (even tho it can't)?

I tried to set it up but i failed. No connection established between both hosts.

Hello. This is me again =)
My lcvpn goes down, when VM containers trying to connect through it.
Thi is log:

iperf on direct connection got 900mbps (1ms)
with lcvpn 500mbps

iperf over internet 600mbps stables between 2 servers(50ms)
with lcvpn 30mbps

Why this diference?

Hi may I ask if the vpn supports VMs within same subnet but across different locations, as shown below:

can I only install the VPN on the 2 servers itself then route packet for all 4 VMs in the 2 servers?

[main]
port = 23456
broadcast = 192.168.2.255
netcidr = 24
recvThreads = 4
sendThreads = 4

[remote "prague"]
ExtIP = 10.0.0.2
LocIP = 192.168.2.2
route = 192.168.2.0/24

[remote "berlin"]
ExtIP = 10.0.0.3
LocIP = 192.168.2.1
route = 192.168.2.0/24

It would be grate to use not only UDP, but TCP/ip protocol.

Hello.
I've got error: "Unable to get UDP socket: unknown port udp/"

It appears after update host kernel to 4.4.0-21-generic.

I've tried to change port to another - same errror.
Any ideas how to fix it?

The lcvpn project looks quite interesting, thank you. I would like experiment with it.

Would you consider changing the license to MIT or BSD (like Go)?

I notice you just write ip packets into the tun device after decryption, is that data will go to the LAN?

in my test case code, the icmp request packet disappered after writtrn to tun

Hello.
I think lcvpn should have -version key.
This feature will help to deploy lcvpn with ansible.

From reading the docs, its not clear to me that its decentralized.

By decentralized, did you mean it supports more than one server to connect to?

It will be awesome if you use stun server tu bypass NAT's

and other awesome option will be to support dynamicIP nodes.

in Europe lot of ISP provide a dynamicIP to their clients.
This is not a problem if you connect to a static public IP node like cloud providers but if we want real P2P Vpn we need to conect to all nodes, lot of these nodes can change their public IP after 1day-week so lcvpn could be resilent to that, something like check every X seconds if the ip is the same if not publish the ip to other nodes using a K/V(there are some public services on internet)
