The bug exists in RouterOS 7.8 too. Additionally my related support ticket was closed by MikroTik without any solution or substantive response.
I made some tests and found that the ping works on VLAN interfaces in both direction even with packet size 1500, but other communication methods doesn't.

This bug is still present in RouterOS 7.2.1 and 7.3beta33 too.

Both config above works well with RouterOS 6 on RB450G and RB850Gx2, but they works only on RB405G with RouterOS 7.
Personally I prefer the switch config variation because the hardware offload works on it only.

I tested it on RB850Gx2 with bridge vlan filtering instead of switch config. In this case the router can be accessed via access ports (ether2-5) on IP but can't be accessed via trunk port. MAC WinBox has worked on both. /interface bridge add ingress-filtering=no name=bridge-lan protocol-mode=none vl...

Hi all, We had a problem with RouterOS 7 on PPC devices (e.g. RB850Gx2) When the config below was applied on a PPC arch device it is unaccessible by WinBox or ssh. It is unable to communicate on IP, but switching and ping is working. MAC WinBox is working too. On mipsbe architecture (e.g. RB450G) th...

RB750Gr3 switch chip does not have full VLAN tagging/untagging support yet, it is planned to implement it in future. Currently, you should use RB750Gr3 switch chip only for basic switching. RB750Gr3 is also powerful enough to handle software based VLANs: http://wiki.mikrotik.com/wiki/Manual:Interfa...

Hi, If you open a more complex panel in WinBox (e.g. Wireless / Interfaces / wlan1 / Wireless in advanced mode) on a lower resolution (e.g. HD) display the panel doesn't fit in the main WinBox window even if it is in full screen mode. In this situation the lower part of the panel is unavailable beca...

Did you try Netinstall? I'd suggest writing an email to support on this one. Usually I have no problem with netinstall, but with these routers there in not any vital sign from them neither from USB the console ports nor the beeper. I tried to power up the routers during I press the reset button (or...

Hi All, In the last two weeks there has been three RB2011 series routers running ROS 6.35.2 dead. The symptoms: 1. If you plug a living ethernet cable to ports 1-5, the LED of port is flashing 2. The ports 6-10 are totally silent 3. The display is lighting fully white. 4. There is no beeps from the ...

Thank you, it's clear now.

Are you using 40mhz extensión channel?

Yes.

Dear Developers at MikroTik, When you set the country of a wireless interface to Hungary there are only 9 channels (2412 to 2452 MHz) available. But the Hungarian regulations according to this document: http://english.nmhh.hu/dokumentum/364/broadbanddatatransmissionwithwirelessdevices.pdf enable all...

Big WARRNING DO NOT upgrade 750UP I have problem on network after couple hours devices just crash some reset by watchdog some not.
I kill my network with this upgrade.

Agree, I have similar problem. If a POE powered device is connected, the 750UP completly hangs. I had to downgrade to ROS 6.29.1.

OK, it's a joke . But there are no honest answare from MikroTik about this MTU issue. Could you tell the position of MikroTik in this case?

OpenVPN server doesn't work. TLS failed appears in the log. Downgrade to 6.10

1. Lack of the ppc support is a barrier to migrate to The Dude v4, because of some of our Dude agents are ppc devices.
2. Native Linux version (at least the server side) would be fine.

I am monitoring ~220 devices (ping, cpu, voltage, temperature, traffic parameters etc.) with Dude 3.6 running on ROS 5.x for a half year. ROS is installed on an Intel D525 dual core Atom platform with 2 GB of RAM and an 16 GB SSD. There are no moving parts. The CPU load usually is at 5-15%, the disk...

Hi, Is Dude development stopped? And what about the v4 ppc version? We are still using v3.6 due to the lack os ppc version.

At now the last working version is 4.17. Versions 5.[12] are broken if you want to use predefined vouchers, see http://forum.mikrotik.com/viewtopic.php?f=10&t=50623 for details.

Same issue on x86 board with User Manager 5.2. Additionally the status refresh (remaining time) of users isn't updated for the next login of the customer even if you reload the page in your browser.

An alternative solution for this feature request:
Add feature to specify credits as normal, but set up an absolute account termination date and time (e.g. 2011. March 25. 22:00)

Hi, We have a feature request for hotspot/user manager system: We have guests coming for fixed time interval (eg. 2011. march 05-11). We 'd like to give access them for this interval terminating at leaving. Please add feature to set up starting and terminating time of access instead of giving credit...

Same result with the latest Nokia E71 software (501.21.001) and RouterOS version (4.17).
