I´m trying to connect two networks over a third Ipfire-instance. The “normal” direct net-to-net connection does not work because one net is only connected by a mobile connection without a public IPV4-address.
Is this a possible venture?
Two networks, both with Ipfires, should be connect via a net-to-net connection via OpenVPN.
A direct connection is not possible because one network does not have a public IPV4-address (connected via mobile LTE).
I already set up a third Ipfire on Hetzner Cloud with a static IP. I want to use this “cloud” Ipfire to connect the two other networks.
If one of the IPFire has a public IP address, then you don’t need a “third instance.”
You configure the IPFire with the public address as an N2N OpenVPN server and the other as an N2N OpenVPN client
I was not precise enough. The net-to-net connection should still work when the primary internet connection fails and switches to LTE Backup. In this case only the “cloud” ipfire has a public IP.
Could this different solution for two machines be viable?
Configure a N2N VPN on both sides and import the client file of the other machine on both machines so that both have 2 N2Ns.
If one machine loses its public IP one NSN stops working but the other still works.
