Попробовал поднять VPN-соединение в локальной сети и вот что вышло:
OpenVPN-сервер, он же роутер:

Вот.
Значит ли это то, что tun0 работает на скорости 10М и выше сделать ее

Русские программисты продолжают улучшать и обновлять свои компьютеры до тех
пор, пока в них не остается больше ни одного свободного прерывания, ни
одного
свободного разъема и места на передней панели. Если возможности к расширению
у компьютера уже исчерпаны, они покупают новый и соединяют в локальную сеть.
