I tried today installing RouterOS-4.10 on x86 Intel
I had two PPPoE interface running
I had one PPTP interface running
Adding OVPN successfully made those PPPoE and PPTP stop running and successfully made an error like this:
… OVPN cannot create interface …
Some kind of bug ?
Thank you
Problem solved.
Its really buggy.
i have to restart, re-enabled and disabled all PPTP interface,
must enabled OVPN first than PPTP,
and now it worked …
OpenVPN is quite new and not tested a lot inside RouterOS. One problem with it is that there is no support for UPD mode.
Strangely TCP mode only is supported inside Router OS, but UDP is definitively the recommanded mode because of the double TCP meltdown problems.
We’ve drop OpenPVN use inside Mikrotik because of this. More, there is no hardware acceleration for OpenVPN inside router OS, so its use is of limited usefullness, except for small bandwith VPN of a few Mbps.
