I set the firewall to block my son's computer Sunday through Thursday, 21:15pm till 9:00, basically over night. I noticed Saturday night/early sunday morning, ~2AM, the Linksys WRT1900ACS running 18.06.2 r7676-cddd7b4c77 is blocking. The time to begin blocking is 21:15 Sunday, not 21:15 Saturday. I go to the Status page and its reporting the correct date and time. Check your router if I'm the only one with this problem.
That smells like a off-by-one error, or different opinions on what the first day of the week is between GUI and Backend... (Sunday is the first day of the week)
You know I don't think this rule work at all. I can still access internet, I use LuCI to setup the rule. I modified the rule for 7 days a week, block all wan to lan using mac addr, all else blank.
How do I fix this, what am I missing?
