Hello friends. There is a small problem, is it possible to configure 4 different networks (Association offices) Protocol tap in nethserver? It is necessary that they were tied together, that would be of any network paputsa in need. Employees should still be connected via tun.
basically I'd say yes, with OpenVPN.
Thank you, everything is read, in theory, turns out Yes, and in fact, it is not clear what settings to put, servers combat, some are for 800 km , now the server work and users for tun.
