Right. I think we’ve got this sorted now. Discussion had moved to another thread for some reason, but the solution was fairly straight forward in the end!
Before running the command above I did a quick check with chkconfig --list | grep -i wanrouter which gave the following
[root@freepbx ~]# chkconfig --list | grep -i wanrouter
Note: This output shows SysV services only and does not include native
systemd services. SysV configuration data might be overridden by native
systemd configuration.
If you want to list systemd services use 'systemctl list-unit-files'.
To see services enabled on particular target use
'systemctl list-dependencies [target]'.
wanrouter 0:off 1:off 2:on 3:on 4:on 5:on 6:off
[root@freepbx ~]#
Turns out this probably was the real fix…
All working perfectly now :).
