x86 upgrade will take a little bit longer and show following script error in log file, while Mikrotik devices not:
DefConf Gen: Unable to find ethernet interfaces (timeout 30sec)

After upgrade from 6.42.7 to 6.43, the L2TP/IPSec VPN between ROS and Draytek Vigor 2920 broken.
It showed failed to get valid proposal and failed to pre-process ph1 packet(side:1, status 1)
Downgrade to 6.42.7 and it worked as usual.

It's not working to use "0.0.0.0" (dynamic IP address) as the "S.A. Src. Address" on IPsec Police.

+1, since v6.30.

Another problem:

Site to Site IPsec is broken.
RB850Gx2 (Dynamic IP) to Vigor2920 (Fixed IP) don't work after upgrade to v6.30.
