Re: IPv6 RA ND with DNS

ROS 6 supports DNS in DHCPv6. Select "Other Configuration" in ND and deselect "Advertise DNS". Then add DHCPv6 server without pool. However, unlike IPv4, you should define IPv6 DNS in "IP" -> "DNS". It can't be defined in DHCPv6 or pool.

Re: IPv6 link local address on vlan interfaces

I can confirm both RIPng and OSPFv3 have this problem in ROS 6.15.

Re: IPv6 RA ND with DNS

Only Apple IOS gets DNS advertisement in RA.
Windows gets DNS in DHCPv6. However, Mikrotik does not support it in DHCPv6 configuration.

Re: v6.15 released

My path to make Routing Marks work.

6.14 -- work
6.14 to 6.15 -- NOT work
6.15 to 6.13 -- NOT work
6.13 to 6.14 -- NOT work
6.14 to 6.7 -- work
6.7 to 6.14 -- work

So weird :?

Re: v6.15 released

After several hours troubleshot, I found the clock problem in the RouterOS 6.8+ will cause Certificates problems. Because RouterOS will simply think remote Certificates are not valid in 1970.

Re: Packet going out wrong interface in traceroute

I solved problem. It's misconfiguration.

Connection mark of IP address A to B not only marks the session of A and B. besides that, connection mark also mark all related traffic. For example, ICMP control traffic from intermediate route between A and B. I missed it.
