Well, from my experiments today I am left totally confused, it is as if the whole access control thing is broken ..
This time I am starting with much the same set of IPs as before but for the Exceptions rule I changed it to use the same schedule (which at the moment should NOT be active as it is only defined for some weekdays, and it is Saturday today..
The first rule (named: 'SslBlock') is set up as follows:
Filtering=Block some access
Logged=No
Schedule=StudyTime (5pm to 9pm weekdays)
IP address ending in 21
IP address ending in 22
IP address ending in 25
Apply Web Filter
Advanced Port Filters
The advanced port filter is set up for the full IP range, Port 443, UDP protocol
The second rule (named 'Exceptions_1') is set up as follows:
Filtering=Log web access only
Logged=yes
Schedule=StudyTime (5pm to 9pm weekdays)
IP address ending in 20
IP address ending in 23
IP address ending in 24
IP address ending in 26
IP address ending in 30
IP ending in 20 is the administrator PC
The following is the sequence that I used in deleting the IP addresses from each of the rules. Whilst doing this I was pinging my ISP to check when I lost internet connection and when it came back:
Step 1) Starting IP setup (above), RESULT: No internet
Step 2) Remove IP ending in 21, RESULT: when hit the save button the router rebooted! Came back up with No internet
Step 3) Removed 22, RESULT: saved OK, No internet
Step 4) Removed 30, RESULT: saved OK, No internet
Step 5) Removed 26, RESULT: saved OK, No internet
Step 6) Removed 24, RESULT: saved OK, No internet
Step 7) Removed 23, RESULT: saved OK, No internet
So at this point my rules are basically:
'SslBlock':
IP address ending in 25
'Exceptions_1':
IP address ending in 30
And I still have no internet access!
Onto the next step ..
Step 8 Disabled the SslBlock rule, RESULT: Still no internet!
Step 9) Disabled the Exceptions_1, RESULT: Internet working again
At this point I haven't a clue what's going on, the access control/schedules seem to be following no logical pattern that I can determine
