Not talking about what you figured out - I am talking a huge difference in a setup when your HA vs when its a single box, etc.. Did you validate pfsense is seeing the dhcp discover? Troubleshooting dhcp is 30 seconds worth of troubleshooting here... The dhcp service is running or its not running, it sees the discover or it doesn't does it send a offer... @Gertjan list is pretty spot on to be honest ;) hehehe

Thanks for the tip, Just opened a Ticket.

Found the problem: the WAN interface kept restarting if 'Speed and Duplex' was set to 'autoselect'. Changed to 'Default', and the problem is resolved.

@luisenrique said in squid + ad auth lookuot ad account: Due to some unknown reason the account used to authenticate squid users in AD is blocked after several unsuccessful attempts to authenticate the account is blocked by AD policies, I have rectified the key in both systems and the same thing happens , I am sure that It is squid, because I change to another account and the same thing happens to me or I establish an account that does not exist and stops, so the users are being able to authenticate themselves to navigate. as aditional information i see in logs basic_ldap_auth: WARNING, could not bind to binddn 'Invalid credentials' i set the password inboth system but it continues see error

Figured it out. I created an IP alias that contained the Student IPs I wanted to connect to, and a Port Alias with the different ports that NS uses, then created a NAT rule with those aliases and now things are working perfectly in the Tutor console from the Admin side. Feeling kind of silly that this didn't occur to me earlier lol. The Tech console still presents some weird behavior but I think that's due to the console's settings, so I'll take a look at that.

@ilbicio Well done! I have total clients connected now! Weeehooo!! Thank you very much. P.S. I hope one day I will learn how to collect OpenVPNusers connection history in Zabbixю

It will be difficult to recommend hardware given your budget, which doesn't include shipping unless you have eBay or Amazon in Africa. That was an important detail missing from the original post and I agree, it's going to be extremely difficult to make any recommendations based on your budget and consider shipping.

2 weeks ago i installed a "Dual SSID" UBI AP AC Pro. I installed the Unifi Controller on a VM DEB10 server , and configured it for the two "Tagged Vlans" Then i connected to a switch port (not directly to pfSense) , but the recipe is the same. You need to keep in mind that the "Controller & AP" talks untagged , so whetever Vlan you make untagged on the port , has to be able to talk to the UBI Controller AP Switch port AP Native : Controller Lan communication Vlan , untagged. SSID-1 : Tagged SSID-2 : Tagged /Bingo

i hope it's okay to reopen this problem, but with the newest pfsense release, 2.4.5, this stopped working. I noticed there is now a GUI Option for $config['system']['no_apipa_block'] but disabling and enabling it won't make it work again. At first the Traffic was blocked in the FW but after adding a rule to allow every traffic from LAN, the log looks better but still strange: [image: 1585301915147-bf4ccb2d-96e8-4179-abf5-4e94d0088165-image.png] It's only sending TCP-SYN?

I'm pleased to see atime is off already on a 2.4.4 ZFS file system install. Yah! [2.4.4-RELEASE][admin@...]/root: zfs get atime zroot NAME PROPERTY VALUE SOURCE zroot atime off local

Version 2.4.5 [image: 1585269109199-561b8465-7df9-4bfb-8f10-b70e9ca01726-image.png]

Well I found this thread: https://forum.netgate.com/topic/135850/official-realtek-driver-binary-1-95-for-2-4-4-release/15 seems to match what I have going on. Thanks for pointing me in the right direction. I have applied the driver and confirmed it is loaded.. Lets see what happens! Thanks ... On review I notice its the same thread you linked to... I like to do things the hard way and found it on my own to ;-)

@casperse Is it a public bridge in the vm or has is something to do with docker? Anyway, I would start another thread here or in Routing.

Well, things get a little more difficult to fathom. I have installed a fresh SD Card into the "faulty" APU2 and now have no errors. For the record, I did originally reboot the APU2, firstly via software, then hardware and the error was still present. Obviously the fault is now intermittent. Anyone had a similar error? or does anyone know what the error actually refers to? "nginx: 2020/03/24 12:06:33 [alert] 52803#100257: send() failed (55: No buffer space available)"

@cobrahead Awesome! Got it, I added one more above that one to allow access from OPT2 to one address on the LAN, for the printer, and it works like a charm! I appreciate your help. How much more involved are vlans to configure?

Is Snort showing any alerts/blocks?
