Re: The sad state of OpenVPN

If the GPL is the issue here, I have a very simple solution: Release the OpenVPN as a package not bundled in RouterOS. Provide a link on the website and be done with it. Saying that Mikrotik has to deal with GPL already anyway (for their modified kernels and whatever else they hack), so having anoth...

Re: The sad state of OpenVPN

One detail I might have missed: I am planning to use mikrotiks as OpenVPN clients (so each device will handle a single connection). Regarding V7 beta is there a feature list? I am cautious with bricking, as I do not have immediate access to a windows box to do a recovery (last time I tried with wine...

Re: The sad state of OpenVPN

As compared to what? To OpenVPN using UDP as transport? In general VPNs using TCP as transport have their own kind of problems on lossy networks, so I'd like to understand better what you actually have in mind. OpenVPN TCP under port 443, no firewall is normally dropping packets to that port or que...

The sad state of OpenVPN

I have an hAP AC2 that I want to use for a permanent encrypted tunnel to a box in datacentre that acts as gateway (as in routes all WAN traffic to it). I already run an OpenVPN server, and initially each client was running an OpenVPN tunnel. Unfortunately Mikrotik seems to ignore OpenVPN and only su...

Re: hAP AC LAN<->WAN gradual slow down [SOLVED]

Final update:

Connected directly to the ISPs RB2011, and the slowdown was there.
All people who blamed the ISP were right, ... maybe (since there is an RB2011 and AirFibre involved in between).

Re: hAP AC LAN<->WAN gradual slow down [SOLVED]

A bit of an update.

Bought RB4011.

With RB4011 the problem is still there but not as dramatic (it drops to about 40Mbit/s intermittently). So WTF is going on...

Re: hAP AC LAN<->WAN gradual slow down [SOLVED]

Are you sure the slowness happens in router (not ISP)? There are some ISPs that throttle (all) the traffic heavily when detecting something they classify as P2P. As the router is single core and CPU usage is well below 50% I would assume it is not the bottleneck (unless queues are configured!). No ...

Re: hAP AC LAN<->WAN gradual slow down [SOLVED]

It seems I have replicated this issue with completely different machine and no OpenVPN. It seems that when the machine utilizes about ~1-5Mbit/s of UDP it causes the hAP AC to gradually slow down. Once I kill the traffic the speed goes back up, and after restart of the UDP traffic it gradually slows...

Antenna gain on a Disc should be set to 21, you are running far too much power for a short link. I could add antenna gain in the interface setting, do you think it is a good idea?

So theoretically Basebox 2 can also be powered from Omnitik 5 AC PoE out, but I will need to buy a Basebox 2 to confirm that.
