Re: Opening ports on router (static IP & NAT)

I have an FTTH GPON connection as well with a bridged ONT (simple media converter). The problem with manual port forwarding is you need to bind each device in your home with a static IP and then you need to manually add port forwarding rules for each of the ports you require, each protocol, each sta...

Re: v7.0beta8 [development] is released!

Can anyone please confirm wheather IPv6 accounting is added to ROS v7? IP(v4) Accounting has been removed in RouterOS v7. So certainly there has been no IPv6 Accounting added. Accounting should now be done using Netflow (IP->Traffic Flow) which already supports IPv6 in RouterOS v6. Thank You for th...

Re: IPv6 configuration on PPPoE interface

I am operating a couple of WiFi networks at company locations where 200-500 clients are connected every day (Android, Apple, Windows, ChromeOS etc) and out of those I see maybe 3-10 that are not actively using IPv6. Maybe they have disabled it somehow. But then, we do not have dynamic prefixes. One...

Re: IPv6 configuration on PPPoE interface

Another small hack I came up with is to reduce the preferred and preferred-lifetime & valid-lifetime to 2 hours in ND>Prefix, it seems to work and forces the client devices to refresh IPv6 addresses every two hours or at least drop whatever it used after 2 hours, but again this is dirty and not a c...

Re: IPv6 configuration on PPPoE interface

Your local systems remembering old prefixes after the ISP has changed them can be considered a RouterOS bug or at least limitation. (it should send an RA with the old address and zero lifetime when it withdraws the old address to set the new one, but it doesn't) IMO, its a bug but yes perhaps a cur...

Yes on the router. But make sure your clients are correctly setup as well. So I have 3 OSes on my clients, iOS, Windows and Android. I cannot disable "privacy extensions" on iOS nor on Android, and on Windows, if it's disabled, router discovery would also be disabled. On RouterOS, I unchecked "Adve...

Re: IPv6 configuration on PPPoE interface

You will have permanent pain when you cannot get 1500 byte MTU and no way to communicate smaller MTU to the client (like in a ND). Make sure you do not set the clients to "managed address" (DHCPv6 client), it will not work. It has to be SLAAC (router sends RA). Also it appears that in some of my se...

Re: IPv6 configuration on PPPoE interface

What are "privacy extensions"? Privacy extensions means the client will not use the MAC-derived fixed IPv6 address structured like prefix:xx:xx:xx:ff:fe:xx:xx:xx but will change IPv6 address regularly. (different random addresses prefix:xx:xx:xx:xx:xx:xx:xx:xx so no ff:fe in the middle and not look...

Re: IPv6 configuration on PPPoE interface

There must be a mistake somewhere. When everything is configured like I mentioned it just works. The reason you can reach some sites and not others when you have this error is that some sites block ICMP (clueless firewall admins) and the same thing happens with IPv4. I've shared my IPv6 config.

Re: IPv6 configuration on PPPoE interface

IPv6 large packet fail This probably means that your internet connection does not have MTU 1500 but a smaller value. Check what the MTU value is and if you can raise that to 1500. E.g. when you use PPPoE there is a Max MTU and Max MRU field in the settings, put 1500 there and see if it works and th...
