and few more other threads in the forum here

Vigor 120 V2 has new firmware (at the moment at main Taiwan) which supports MER

Hmm, http://www.draytek.co.uk/support/guides/sky-mer-setup-guide
It's a bit late but useful at least

btw I had a read of those release notes for the 120, the vigor 120 will work with old firmware since it will just be passing dhcp packets through from the router behind it, so not sure what they would add for supporting that

I got my 2860 connected using the guide from Draytek.
