This is a little off-topic from the opening post, but Google sent me here because of a similar problem: getting a USB serial console working on a PL2303 in RouterOS 7. For any lurkers trying to find an answer for a USB Serial port on a hEX 750Gr3 running RouterOS 7: I discovered that after upgrading...

I am very pleased to see netmap listed in 7.1 in /ipv6/firewall/nat, as @Thoru pointed out. I'll be playing with this to see if I can get it to work as I would expect it to.

I decided to try out ROS 7 beta on a CHR in GNS3 just to kick the tires a little, and was sad to see that there's still not 'nat' tab in the IPv6 firewalls menu. Oh, sigh. I was hoping, but alas. Thanks for checking on this. ZeroByte, thanks so much for chiming in! Your comments are always so infor...

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...

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...

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...

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...

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?

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...

*) fixed problem where switch locked up after a while and only small packets could be sent;

Hooray! I've been waiting for this fix for a long time.

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 ...

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 ...

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.

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 ...

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...

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.

Please add my +1 vote for ECMP, too.

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...

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...
