Re: Feature Request: IPv6 NAT66 Support

Is NAT66 the same as NPTv6, though? I believe they are a different concept, different RFCs even. You're right: NAT66 is not the same thing as NPTv6. The Opening Post originally asked for NAT66 six years ago, but many people in this thread have asked for NPT instead. NAT66 is the stateful port trans...

Re: Feature Request: IPv6 NAT66 Support

Once again, I had to change all IPv6 addresses for services on my local network because Comcast changed my /60 for what seems like the sixth time. I am quite tired of this, so this time, I defined a ULA for my local network instead of changing all of my servers' addresses and reverse DNS zones to th...

Re: iOS14 "Use Private Address" Random MAC (Default) and Time Restrictions

Since the second-least-significant bit of the first octet indicates it is private, I started denying private mac address access to my WiFi networks in capsman with an access-list deny rule. I wish I could give them an error that tells them that private Wi-Fi addresses are not allowed. /caps-man acce...

Re: RB4011 high, uneven CPU load and a crash.

Mikrotik Support analyzed my supouts and says that my problem is still hardware and wants me to RMA again. RMA roulette is not a very fun game to play. It is even more painful because I made the mistake of buying from a random Amazon Marketplace seller who had a great purchase price but who has pret...

Re: RB4011 high, uneven CPU load and a crash.

I have a hunch this might be caused by the L2TP client. Are any of you seeing this issue not running an L2TP server or client?

Re: RB4011 high, uneven CPU load and a crash.

Sigh, the new RB4011 that I received as a replacement for this problem started doing this today, too. The profiler gives no clue as to which process is actually pegging a core. It hadn't fully hung yet when I caught it, so I actually got some decent supouts as it was happening this time, so hopefull...

Re: L2TP with IPsec MTU settings

The default in RouterOS for L2TP is 1450. I was confused about this too because I can enable IPSec over L2TP with the same default MTU, and it still works without dropping packets. My IPSec configuration has been negotiating cbc(aes) + hmac(sha512) encoding. I have MRRU off, and the ESP packets are ...

Re: CSS326-24G-2S+RM hangs until power cycle

This just happened to my CSS326-24G-2S+ running 2.10. It started balking after 17 days of uptime. Pings were fine, but any serious traffic would hang after a packet or two. Now that I think about it, it seems like maybe the ping packets were small, and larger packets would hang, maybe? I don't know ...

Re: RB4011 high, uneven CPU load and a crash.

After opening a ticket with Mikrotik Support, they determined that the cause was faulty hardware. They are aware that some RB4011 hardware has flaws that can cause this and the warranty should cover a replacement.

Re: RB4011 high, uneven CPU load and a crash.

I believe this bug has also bitten me. CPU goes to the extreme, and eventually, the system grinds to unresponsiveness. It doesn't reboot; it just sits there constipated. Maybe it could be a thread leak? It is syslogging to a remote server and there aren't any errors. Instead, it goes silent without ...

Feature Request: Reverse DNS support

TL;DR: Please: add a reverse-resolution option to monitoring tools let the DNS-update tool submit PTR records let the IPv6 DHCPv6 server provide the RFC4704 FQDN field to the binding-script. I believe that both forward and reverse naming every device brings order and humanity to a well-designed netw...

Re: Dynamic DNS PTR updates for reverse zones

It has been a year since this post. I wonder if anyone at Mikrotik has ever noticed it? Why are they so silent on this?

How about simply adding a dns-update parameter to let us specify the record type instead of always updating an A record? One would think this would be a relatively simple change.

Re: RouterOS v7.0 beta1 - when?

I do require more IPv6 functionality (like policy routing, hopefully also NAT66) somewhat urgently for a production environment, not really the place to run early beta versions. Best would be when that appeared in v6 but as I understood, no more work is being done on IPv6 in RouterOS v6. That is no...

Re: Feature Request: IPv6 NAT66 Support

There is a real need for RFC6296 IPv6-to-IPv6 Network Prefix Translation. No, this is not Port Address Translation or Masquerading. It is straight, simple, 1:1 prefix swapping. It takes simple bitwise operations to swap prefixes. No connection tracking is required. No state is required. No, this isn...
