Re: Phones on UDP over OpenVPN

We have solved similar problem with UDP packets going through VPN over 3G. If VPN was disconnected, UDP packets went through public internet but as soon as VPN was up, UDP did not return to VPN. It behaved the same way as you describe. We have solved it by setting UDP stream timeout to 1s in connect...

Re: Winbox 3.10 released!

Normis, it seems from screenshots, that conrad uses other than default text size setting (which in fact works with font DPI).
