Alright your connections are working, they are connected.

See both IPSec SA established in logs.

If you still can't ping between the two that probably means
That your firewall rules are droping the packets.

You may need to add a rule to your firewall like this.

iptables -t filter -A FORWARD -s 192.168.0.0/16 -d 192.168.0.0/16 -j ACCEPT
