In the Web gui of Openfie 3.2.0 at the STUN server setup it says one needs TWO PUBLIC IPs to be able to use it.
Is this really true? Does this mean, that the typical one-internal (192.x.y.z) and one external (“official” routable Ip) is NOT enough?
Why should ones server have two public IPs anyhow???
Pls clarify, thx
