Hi xvo, Thank you for your kind reply. :-) Yes, i have tried both these settings. I have even tried to disable all eight RJ45-interfaces alltogether, only using the SFP ports. The LEDs are still flashing red when i plug in a low voltage (24V) power supply, in power input 2. It seems like the flashin...

Hello mutluit, Thank you for your reply. :-) As i understand from this thread: https://forum.mikrotik.com/viewtopic.php?t=94788 It isn't so simple. I tested it on mAP. It seems to work for one day on two, but in a long period USB power will return enabled randomly before the duration requested from ...

Hi krafg,
Thank you for your reply.

These are my LEDs under "System -> LEDs":
Unfortunately, it does not look like I'm able to disable the PoE-leds flashing from here.

Hi guys, I am using MikroTik devices in industrial environments, where one of the requirements is that all networking devices can generate alarm signals for use with PLCs . This must be a potential free relay output, that can be monitored using a PLC digital input. Conditions that trig this alarm ca...

Hi guys, Is there any way to disable the "All PoE LEDs flashing" due to low input voltage? I want to use the second input with 24V for redundancy purposes, without the need for PoE. The device seems to work perfectly fine with 24V input on both power supply sockets, and it would be nice to...

Hi guys, You should double-check your NAT-rules... I use the «destined for not-private-subnet » (!192.168.0.0/16) -approach as matching criteria for my NAT-rule, this NATed my OSPF multicast traffic. The destination broadcast address 224.0.0.5 is used to send Hello packets to all OSPF routers on a n...

The auto-updater accesses download.mikrotik.com using port 80. You'll need a firewall rule allowing your output chain internet access to destination port 80.

That... is probably it. Of course...
It will select some random high port as source port, and match it as established. I understand now.

Thanks, pe1chl and Anumrak!

Hi Anumrak, I don't quite follow... Du you suggest that i narrow down my firewall rules by selecting an interface? I have other routers conneted to all interfaces of this device, and will want LDP to work for all of them. I have the allow TCP 646 output firewall rule on top of my list, and the count...

Hi guys, According to RFC 5036 section 3.10.1 , LDP uses TCP and UDP port 646 for its communication. I have created 4 firewall rules for this: action=accept chain=input dst-port=646 protocol=tcp action=accept chain=input dst-port=646 protocol=udp action=accept chain=output dst-port=646 protocol=tcp ...
