Here is the output, no IPs in it to hide:

Was that output obtained with the failing SNAT line in the snat file?


[root@server ~]# shorewall version
5.2.2

In /etc/shorewall/snat  line#2:

SNAT(!9.9.9.9)  12.12.12.12/29 enp2s0

is hashed, shorewall does not start with it.
I feel I miss something. The documentation deals with old versions of
linux kernel while Fedora is updating very often.
I will provide any other info which might be needed.
Thanks for Your response.

I need to see the actual error message that you are getting (in context).

As I have explained, shorewall does not start with this line in SNAT unhashed. The error shown with 'systemctl shorewall status' after unsuccessful shorewall restart is something like: .... cannot start, unrecognized record in /etc/shorewall/snat line #... The record was even listed: SNAT(!==IP==). I am afraid to repeat this situation again as the connection may die out and I should run to the place to fix it.

IPSec tunnel is working, I presume, in 'ipsec whack --status' connection list shows:
  Total IPsec connections: loaded 1, active 1
The tunnel is not routed to the LAN IP range however.
