Hi again! :-)
I enabled a tunnel, but the connection did not come up, although the other side is online, too… Dunno why the tunnel does not connect, was functional in 2.1.x, but disabled since then.
On the 2.2.6 pFsense I have in the log:
charon: 08[IKE] <con2000|1>sending retransmit 5 of request message ID 0, seq 3
Debugging IPsec is no fun….
What is this widget-thing? I didn't install anything!</con2000|1>
