David,
Interesting idea. I never tried it myself, but I just played around with
it and confirmed that it would work. The time has to be converted to
UTC, so based on your scenario, and assuming you live in the ET timezone
(currently -4 UTC), you could do something like this:
iptables -I FORWARD -m mac --mac-source AA:BB:CC:DD:EE:FF -m time
--timestart 01:00 --timestop 10:00 -j DROP
Obviously you would need to change the timestart/stop for a different
timezone and use the appropriate MAC address. And you could stack rules
for additional MACs. I don't believe you can use wildcards for MAC
ranges, which might have been a good solution if all the iDevices shared
a common OUI, so you would need a rule for each one. The above rule
would block access to the Internet, but still allow internal network
access (which wouldn't go through the router anyway).
I imagine the best way to implement this in Astlinux would be to insert
the rules into /mnt/kd/arno-iptables-firewall/custom-rules

Has anyone used iptables to block internet access for a specified
device between specified times. It looks like iptables has a
capability to match against time, but before I experiment I thought I
would ask if anyone has the necessary commands figured out already.
Basically I want to impose a curfew on internet access for the kids
iDevices, say between 9pm and 6am every day. I could identify the
device by mac address.
Any suggestion on how to go about this in AstLinux?
Thanks,
David
