You can prepend most IPtables rules with a '!' to reverse their meaning, so, a rule to reject all traffic that's not a certain mac address:

So... I have this other crazy idea. What if I want to simply block the neighbour's wireless based on time of day? Would it look like this?
If it is supposed to look like that, then would I get away with it knowing to go from 11:30pm to 7:30am the next day? Or would I have to make two separate rules like this?
One other question... you had my wheels turning when you said I can reverse the meaning by putting in the ! in the iptable rules. I have the flu/cold right now, so I can't think straight.
Is it possible to block ALL internet connection after 11:30pm, no matter where the connection? I assume so. I think I'm over complicating things in my head. I have yet to talk with my friend, but I want to give him all the options of what he wants to do. Perhaps that's what he's really looking for. No connection anywhere at night when his son would be alone on the internet (like if they're on vacation, etc).
Okay, I had a little bit of clear in my brain fog, and I think I missed the obvious. I am assuming that if I want to block the Android from accessing any internet after 11:30pm, I would do this (everything but the MAC address):
I'm not sure why I thought of this sooner. I was obsessing on how to block access to the neighbour's wifi when I didn't even realize I could block the Android from all internet after 11:30pm, which I think my friend might like that idea best (like I said, for if they're on vacation, travelling, his son sleeps over at someone's house etc).
I'm *actually* just starting to understand iptables now. I feel so stupid. It's like learning to read the first time, LOL!
You're right about the --weekdays code though. I tried it with days, and the rule would apply-- I was getting an error.
I tried the rule by itself (no time) and it blocked me off of my router (and I assume every wireless AP). However, I can't get it to work with the time rule. The rule will apply fine, I'll reboot, but I still have access to the internet. I was going by my Android's time. I would set for a time that would give me enough time to reboot and still have access. That time would pass, and I would still have access to the internet.

Figured it out! I opened the terminal emulator, typed
And it gave me the date and time. It was giving me GMT. So all I had to do for the iptables rules was add 4 hours (I'm Atlantic Time in Canada).
Worked like a charm.
So my rule for the phone (if that's what my friend wants) will be

I do have one more question, though. I don't have data, nor does my friend's son, but in case there is a parent or someone reading this right now that wants to do something similar to what I did, and they are dealing with a phone that DOES have data, will iptable rules apply to data as well? I assume so... but I just want to make sure.

I'm having problem with an iptables rule. It seems that on one of two systems on the nat table, the INPUT chain doesn't exist for some strange reason.
I get the error below:

Generally, most people, I guess, go from 5.3 ML4 Directly to TL 7. So they may never run into this issue.
