Yes I looked at this page but i am not a VPN specialist !
What is confusing there are only examples with RUT, with public IP addresses.
Idem for Openvpn: always examples with two instances
When I read "two RUT routers of any type" then I stop my read !
And the notion of certificates is not addressed.
In fact, what I want to do corresponds to the "configuration schema 2" : two sites, independant, with several PC, NAT, with same local lan range(192.168.1.0)
Shall the local IP addresses different ?
Shall I also fill the openvpn tab as client and reference the certificates here ?
Are the certificates in PKCS12 format supported ?
