densen2002 ,
Thank you for your response.
I bought three mikrotika hex750gr3. joined them together VPN tunnel l2tp + ipsec, configured routing, vpn, all participants can see each other, i.e., You can access the camera from a computer in the country of a city apartment like inside the LAN, i.e. locally. cottages or have a closed channel up encrypted file storage.
close ports for access from outside the local network and VPN to the network nodes, routers, etc. NAS'u
which was to be implemented.
What there is a way to measure the speed of communication within the VPN tunnel?
And I do not understand about the L2 and L3, ie, I realized what level otnostitsja?
