PW48V-12V85W - which CCR are r2 CCRs ?

Hi, I wonder, if somebody can shed light into this. Mikrotik now offer a -48 - +48 V PSU for, what they call "r2" CCR routers. The funny part is, that the Mikrotik.com page references CCR1036-8G-2S+ and CCR1036-8G-2S+EM as related products (which would be great), but pictures in the brochure indicat...

No IPV6 on PPPOE clients after upgrade to 6.43.14 and 6.44.2. Sad... My problem is on the server side. Does DHCP work at all ? Can you do a configuration export or does it hang ? IPv6 on PPPoE would be affected by the DHCP problem above, as it relies on DHCPv6 pushing the IPv6 details over PPPoE. /M
