1-)
System->SSH Access: 
'Set SSH port to default 22' is ENABLED, whereby the wiki indicates ... 
"SSH in IPFire
The Internet Assigned Numbers Authority IANA has allocated port 22 to the SSH protocol, but IPFire runs SSH on port 222 by default because of security reasons."

Note that a restore from the prior core backup, that had this previously disabled, does change it.

2-)
Network->DHCP Server:
DHCP values for BLUE, such as BLUE dhcp enabled, are not set from a restore of previous core backup.

3-)
Network->DHCP Server: 
List of fixed leases not imported via restore from previous core backup.

4-)
IP System - Snort/VRT GPLv2 Community Rules were ok on previous core 164.
On 165 test they show up as one of the providers, and a forced update sets the date, but the ruleset does not appear when clicking 'Customize Ruleset' 
Deleting the provider, and adding it again, and doing a 'Force Ruleset Update' for it did not help.

Emergingthreats.net Community Rules: ruleset were present, but none were checked. Enabled each rule and everything ok for that provider.  Same for Abuse.ch SSLBL Blacklist Rules

5-)
Firewall->Blue Access:
Wireless configuration "Devices on Blue" is blank even after a restore from previous core backup.
