Необходимо настроить VPN канал между двумя локалками, каждая подключена к inet через прокси сервер на FreeBSD (squid, ipfw,natd).
Для организации канала хочу использовать программу mpd.
Какие надо прописать настройки, какие порты надо открыть в ipfw???
настроил на одном конце mpd-server . с компами из вне кооторые имеют реальные ip всё работает прекрасно . а вот из под nаtd не работает
вот лог mpd
