ipsec Net2Net to ipfire

[mts]

Hi guys,

i would like to connect an opnsense to ipfire by ipsec RSA.
Is there someone who maybe has an step-by-step instruction what to take care of?

How can I import the CA from ipfire (pem-format) ?
How can I export the cert from opnSense so I can import it to ipfire?

THX
