Ребята, подскажите, что где обновить\заменить? спасибо:
client:
Linux ubuntu 4.2.0-16-generic #19-Ubuntu i686
go version go1.5.1 linux/386
govpn-4.0
server:
Linux 3.19.0-31-generic #36~14.04.1-Ubuntu i686
go version go1.5.1 linux/386
govpn-4.0

Сгенерил айди, поднял сервер: govpn-server -bind *.*.*.*:9999 -mtu 1472 -proto tcp
main.go:88: Server started

Подключаюсь клиентом
govpn-client -key client -id ID -iface tap10 -remote *.*.*.*:9999 -proto tcp -mtu 1472

с обеих сторон вижу:
client: tcp.go:83: Handshake completed
server: tcp.go:92: Peer handshake finished

на сервере 172.16.100.1/24
на клиенте 172.16.100.2/24

Соединение поднялось, все ок.
Пытаюсь с клиента ping 172.16.100.1 и сразу получаю:
