What VPN solution is the best/advised choice when doing a Net to Net with 2 IPFire solutions.
I would follow the information given in the IPFire documentation about how to set up each end of a n2n connection between two IPFire’s.

Hi Adolf
thanks for the link and the input. So openvpn is the suggested variant for n2n in IPFire. Good to know.
Sorry, I misunderstood your question. For some reason I had it in my head that you had asked about openvpn n2n2.
Sorry for that.
You are asking about whether to use openvpn or ipsec or wireguard.
I would say that if you want both simplicity in setup and likely best throughput rate then wireguard is your best choice.
Openvpn is relatively simple to set up but tends to not be as good in throughput due to its overhead.
IPSec has reasonable throughput but can sometimes be more challenging to setup.
The choice depends on the requirements you have for the n2n. If you already are using one of them for RW connections then it might make sense to also use that service for N2N, although you can use different services for N2N and RW.
There is a VPN comparison page on the wiki which might answer your question:
I personally prefer IPsec because it is very compatible with all sorts of third-party solutions and Wireguard is super easy to set up, too.
