Site to site IPSec, pfSense 2.2.5 with IPCop 2.1.9

[kfm]

Hi,

Unfortunately my search didn't show up any result.

I have to connect a pfSense to an IPCop by site2site IPSec with certificates, without success.

Tunneling of two pfSense or two IPCop with certificates work well but I can't get a mix of these running.

I think I din't find the proper way concerning the cert exchange and tunnel setup. Both types of sytems are so different to configure that my experience does not help at all.

I am looking for a how-to or tutorial, which I could follow. That would be a perfect starting point.

tnx very much in advance!
