FreeBSD disable any automated outgoing connections

[freebsd at tango.lu]

Hello,

I have these connections 4-5 am in the morning going to bytemark, 
cloudfare and other cloud providers:

   - Connections  2.0 - Payload 5.0k -
      Ports        | Sources                   | Destinations             
  | Services           | Protocols | States        |
      443   100.0% | 192.168.1.5#1        100.0% | 104.16.45.99#2      
50.0% | -           100.0% | 6  100.0% | SHR    100.0% |
                   |                           | 104.16.44.99#3      
50.0% |                    |           |               |


This machine is an IDS it should never make outgoing connections ever. 
How to disable this?

I have found some older mail on the list that it is some package 
checksum verification in periodic.conf I disabled it didn't work so I 
have changed the ServerName from update.FreeBSD.org to 127.0.0.1 in 
/etc/freebsd-update.conf something still tries to connect out.
