Diversion is better suited to blocking a website via hostname instead of trying to block individual IPs that can be affiliated with multiple websites (and a website can have multiple IPs).
I tried nslookup and it shows one ip address.

Is there a website I can use as a example to test skynet that it's working correctly?
 
Also does it matter if my IP address is in RED?
IP Address; (192.168.1.4)

Your first issue is that your ISP modem isn't in bridge mode and you are running a double-nat situation.


You will be unable to block this IP in Skynet effectively because its hosted on a CDN. We whitelist some major CDN's by default to prevent false positives. You will need to use something like diversion instead.

Lastly im getting the "tail " error, unsure what this means(when trying to debug)?

What is the output of;

Code:
firewall debug info

i enabled them, should filter traffic be inbound outbound or both.?


Should i just reinstall skynet as it might have not installed correctly?

Not sure if you manually disabled a lot of those settings or if your config somehow got corrupted, but in any case I would uninstall/reinstall and start fresh as many are incorrect.
 
Hi Adam, I've noticed a problem with the logs, multiple events are being logged on just one line with the date and time missing on all but the first event, see below.
Code:

Recently I've run the latest Skynet (Version v7.2.2 - 9aae16544adf0c1c4a20b67dfdba9e00) and Entware updates. This is on my RT-AC87U running Merlin 384.13_10 with Scribe and UIScribe, it also happens on the skynet.log file.

I've rebooted the router just in case but it still does it. firewall debug info shows 18/18 Tests Successful.

EDIT: fixed it by reinstalling Scribe.

Probably a dumb question but would skynet work with VPN traffic? ie..block IPs?
Depends what you mean.
* If you have a client device on your LAN/WLAN that is individually connected to a remote VPN, then the traffic is encrypted and neither the router nor Skynet will see or do anything about the traffic (internals.)
* If you have a VPN server set up on your router, as well as Skynet, and are connecting to that server from other devices remotely while away from home, then that traffic would be protected by Skynet (and Diversion, etc.) (This is what I do.)
* If you have a VPN client set up on your router to send *all* of your traffic to another VPN server somewhere... I don't know. Not sure the order of operations there.
 
I tried to install and it hang forever at "Creating SWAP File"... I tried deleting the scripts but that didnt help. After this failed about 10 times I just installed FlexQOS from AMTM so I know the router can install things fine.

any ideas? thx!
 
It takes a long time to create a swap file. How long did you give it? What USB drive are you using? Is it a new drive?

thx, I let it run while I slept... it finished

One more Question

I want to block specific web sites (like YouTube) from ONLY my kids devices (specific IPs and/or MACs)

Can I easily block URLs from only some devices? (ASUS built-in Firewall block URLs for ALL devices.)

thx

Take a look at the parental controls section of the router. That may be what your looking for.

You will need to find a DNS based solution.

I'm surprised this is not asked for frequently by people. I suspect it would be highly used feature that solves a lot of Parental Control problems. Basically just : 'These 5 devices can not access these 15 websites.'

Parental controls are a losing battle, any slightly tech savvy kid can and will bypass them weather it be via VPN, Proxy or Encrypted DNS

Hi, I encounter the same problem as poster on #7,585 regarding update of blacklist with error " Consolidating Blacklist | curl: no URL specified! curl: try 'curl --help' for more information...."

I understand that his problem was that he had tried to import list in wrong format - list like in hosts format my problem is that I tried to import list in "good" format but still got the same error.


Reading around the forum I found that if I just import this list through amtm/skynet/import IP list/blacklist - this list will not be updated on daily bases but is 1 time import only - I did it this way and everything went fine, but later on when I found that I need to import it differently (if I want automatic update) I use the following command:

firewall banmalware https://iplists.firehol.org/files/firehol_level4.netset

I got before mention error.

What I am doing wrong, and what is the correct way to import new black list which will be updated regularly (I set update to be on daily bases)?
Also will that list survive reboouting of router (when someone advise how to import it correctly - so that it will be added to 13 default lists)?

Thanks

Young kids 6-12 wont know those things, and mine are not 'techies' ...they just watch videos and play games

The malware blacklist feature requires a filter list as input, not an IP list.

Also will that list survive reboouting of router (when someone advise how to import it correctly - so that it will be added to 13 default lists)?

Using a custom filter list will replace the default one included that is linked above (and will survive reboots etc)

Gotcha, in any case a DNS based solution is your best bet.

Thanks for your answer, but I still don't get it completelly...
How I can add https://iplists.firehol.org/files/firehol_level4.netset to be the 14th on default filter list (I don't want to delete or damage default list - is it even possible to add lists to default filter list if yes how)?

Using a custom filter list will replace the default one included that is linked above (and will survive reboots etc)

Does this mean that my 1 list will replace 13 default lists?

Thanks
 
on the lame side of things. how fast does the thumbdrive needs to be? does it have to be a USB3 drive or a old USB2 @ 2-5mb/s will do?
