Yes, had to learn other software, Vyatta, to run IPv6 as it should be. Would prefer to just use RouterOS but even release seem like beta at moment. As mentioned I can not talk up Mikrotik and then have little things cause issues and look foolish.

Install in VMware. The 24hour demo is good for lab work. When done with lab revert to fresh install snapshot. Is not good for routing traffic but is good for learning and testing. I prototype setup all the time in VMware before move to real hardware then is easy setup.

More QA always good. Mikrotik need to make beta for each release with longer testing. Would prefer longer time between release with less bugs rather than fix one, create new one.

If subnet is same then change local subnet. This should not be problem.

I have got RB433AH and the behavior is same as in case of RB450G. So this seems to be a general problem of all RBs. The must be a bug in the RADVD daemon, because it claims that RA packet has been sent but no packet appears in Wireshark. Devs, please provide some fix. RA is key feature of IPv6. I c...

Try this /ipv6 firewall filter add chain=forward in-interface=eth04_LAN2_WIN-HyperV1 action=accept disabled=no comment="Allow local lan" add chain=forward src-address-list=TRUSTED-IPv6 action=accept disabled=no comment="Route trusted hosts" add chain=forward protocol=icmpv6 actio...

Can you post router config and how network is set up?

edit because I was tired and forget IPv6 not need nat

With new RouterOS just put two gateways in default path. If one has more bandwidth then enter twice. You can tell to check gateways with ping. It switch to other if it does not receive reply.

Is a very interesting board. I like the many gigabit interfaces. How much are they?

He pays for your service and if he does not pay he gets no service, simple. Why is there a problem with this? It is the way business works yes?
