Ps. I'm not this hot by far in real life, but frankly, when looking in the clouded mirror, while looking for my glasses and a touch of imagination, I'm frankly not that far off, to be true... That, or it might be time to pay the optometrist another visit

Great news, good feature ! Will it be possible to do a one shot reload of the current whitelist to add comments too or it is too difficult ?

Existing entries on all sets will have to be removed and readded if you wish to add a comment. Banmalware/ban country/list importing will automatically convert current entries upon their next run.
The only entries that won't have comments is autobans, I can't seem to find a good way to pass comments on as they are added by an iptables rule which doesn't support the feature. Besides that everything else will convert seamlessly upon upgrading.

My skynet seems to be running an update roughly every 6 minutes or so according to my logs. How can I change this? I only used your default install stuff so I didn't make any changes.
Thanks

Oh just ran a debug info and found "Duplicate Rules Detected In FILTER"! Is this something to be aware?

I can't think of any reason a rule would be in the same chain twice, as once IPTables matches a rule it moves on. But lets find out whats causing it, please post the output of;

Thanks, I had a typo in my SSHBFP rule removal so they weren't being removed correctly, I'll have a fix out in a few minutes. (not a major issue so don't stress too much).
Edit; 5.0.7 is live

I have duplicate rules in filter for a long time too. I've just updated to 5.0.7 but there is still duplicate in my filter.
After updating to 5.0.7 there were no duplicates rules but after 2-3 minutes they appeared again.
here is the output of iptables -L
my vpn client 1 is active may be it is related.

Your VPN rules in iptfromlan and iptolan are being duplicated 4 times, not really sure of the reason for this as I don't use the VPN functionality. My guess would be that it has something todo with the 4 lan ports but even then I don't see why the exact same rule would be used.
Oops, didn't realise I was using the entware version of find. Use "update -f" to force update to the latest version which will fix it.
Looks like you didn't have the firewall active at the time (it looks for the sets to flush but because they aren't loaded it spits out an error)

Everything looks normal, why do you think its running every 6 minutes?
It's a bug in the ipt_account module, which is unable to delete an existing rule when stopping an OpenVPN instance. It would take someone familiar with netfilter kernel code to debug this, as I can't figure out what's wrong, and the author of that module disappeared years ago. He didn't even answer any email when I was trying to fix his module not working at all on 2.6.36 (I at last managed to fix that particular bug back then).

The logs look fine (besides the crond print not being removed which will be fixed in a future update).
Right now Skynet is saving hourly as it should, and is taking 4-5 seconds to issue the command which is to be expected.

When it saves my entire network stalls for a minute or two. Also, what did I do wrong or should I be following to ensure the firewall is working in this process? All I did was install the script etc.
Thanks

Define "my network stalls". This briefly has an impact on CPU usage, but should not affect your connection (especially to the point where its noticeable to the end user).
Also, beyond that 4-5 second save period, Skynet doesn't do anything until manually run or until the next save command is run. Most of the leg work is handled by IPTables, so I'm not even sure its possible for it to "stall" a connection for minutes after its been executed.
Everything looks fine to me, if/when there is a problem we can give advise from there. But for the most part the current version of the script is stable and there are no known issues that should affect users.
