standard ssid/passwd? WPA2?
same with stock firmware?
working fine here with merlin's .17

Correct. In fact the ssid is similar to my main wifi network and the password is almost the same for testing purposes.
With stock firmware I haven't test it because I'm using Merlin since day one

Edit: i just formatted again and configured everything from scratch.

Miracle... It suddenly started working. Then I installed YazFi and it worked better

I really don't know what can happened, but I suspect some nvram broken var or something...

How much time does YazFi waits to get applied?
Guest wifi is working now, but after a reboot it doesnt appli YazFi settings. I have to manually apply them

60s after a firewall-start is called

Well, now i'm facing another problem.
I can connect to guest network, but i don't have internet access.
It gets Ip correctly, but haven't access.
I think when i manually restart VPN (i'm redirecting guests to VPN), it starts working

Edit: I was so happy that guest networks started working that I forgot to set "auto start on boot" on vpn client... That way, yazfi was redirecting traffic to a disconnected vpn

I'm so sorry...

Everything working fine right now!!! Thanks yo everyone

At least you know the Merlin VPN killswitch works as intended ;-)

Hey Jack, when I reboot the router I have to manually go to ssh and do a "YazFi startup", otherwise the YazFi tab won't show anywhere.

maghuro · Jun 12, 2020

The configs are properly applied, only the tab isn't mounted

what does syslog show?

Need to reboot it later when everyone's sleeping

In the meanwhile, what's for the "&" present on each of your startup scripts line?

/jffs/scripts/YazFi startup & # YazFi

How can I grab the log via ssh and filter everything with "YazFi:"?

Here it is. Note that on the meanwhile I forced a YazFi startup via ssh:

Stale lock file is concerning. Can you double check you're running the latest? This was added prior to merging v4.0.5 but I don't know if you were running a develop version? https://github.com/jackyaz/YazFi/commit/ac77ad5d574782dd76c89309b2dc127de1a643d2

I'm using master, and latest one (with that 10day old commit), as I reset the router yesterday and configured everything from scratch, including installing your scripts.

v4.0.5 is now available!
Changelog:

Code:

NEW: YazFi now supports user/custom scripts. Simply save them to /jffs/addons/YazFi.d/userscripts.d with .sh as the extension, e.g. myscript.sh

I wanted to reply to let you know this meets my needs for the UDP Boradcast issue since I can now just add a script to ensure the broadcasts are tracked and allowed whenever the firewall is reset.

SammyG · Jun 15, 2020

Is it possible to enable YazFi and still use the same DHCP pool as the main network? Would it still be able to restrict traffic between the main LAN and guest networks?
