Port 389 request from known address, unifi?

Hello everyone,

I have a couple of Unifi Accespoint from clients in my controller. So different location.

From one location i am seeing logs in my firewall log.

The IP is trying to connect on port 389, which is dropped.

I am pretty sure it is coming from the Unifi Outdoor+. When i reset the unit, the are no new lines in the log from that IP.

It is not really a known port for unifi:

Port 389 is an LDAP port, also known for being hacked.

But the location i am talking about has only got 2 computers (which i checked with netstat -a) and 1 NAS. (and are off at the moment, except the NAS)

They don't have a server or anything like that.

Should i open port 389 for this location?

There is not really something that is not working, but the firewall lines are annoying :P

Maybe i am being paranoid/over active, but i am trying to explain all the firewall drops coming from known addresses.

Small other problem, STUN port 3478 is a Unifi port. I have created a Dnat rule (a group with all the unifi ports) and they all work except the 3478. That one is still being dropped according to the log.

  • why you have to open this ports? let it close and look if something not working. its correct that 389 stands for ldap. is there an ldap server on the nas? different networks? but its the wrong board, if you wonder why the ports are coming from the ubnt aps.

  • No ldap on NAS. Well i am also curious how you guys look at the Firewall log. Is it common to wanna fix all the known addresses entry drops? :p

    I understand if i really wanna know for sure about port 389 i have to go the ubnt forum. But lot of people here also have got Unifi AP's.
