• Everything went smoothly
• I encountered an issue after the update (please post about the device, configuration, and unexpected symptoms)
• I encountered an issue, but solved it (please post the solution)

If you experience version related issues, then please send supout file from your router to support@mikrotik.com. The file must be generated while a router is not working as suspected or after some problem has appeared on the device

Please keep this forum topic strictly related to this particular RouterOS release.

@EdPa

system - do not attempt to use FastPath RPS on non-ARM64 devices (introduced in v7.21);

@EdPa Isn't RPS only supported in ARM64 devices?

[alibloke]

@EdPa

defconf - improved firewall rule for local traffic to the loopback interface;

Can you tell us what the change was here so we can update our existing firewall rules to match?

[buset1974]

The issue with BGP-VPNv4 redistributing "other BGP" multihop routes to other PE via RR is still occurring in version 7.21.2 [SUP-207808]

[CGGXANNX]

See this post:

Buying - RB1100AHx4 Dude Edition - Questions about Firewall

Also removed connection-state=new on forward drop: Changes: 7.21: filter add chain=input action=accept dst-address=127.0.0.1 comment="defconf: accept to local loopback (for CAPsMAN)" 7.22: filter add chain=input action=accept src-address=127.0.0.1 dst-address=127.0.0.1 in-interface=lo comment="defconf: accept to local loopback (for CAPsMAN)" 7.21: filter add chain=forward action=drop connection-state=new connection-nat-state=!dstnat in-interface-list=WAN …

And you can use @rextended's script to automatically update the defconf rules:

@ferferga

Isn't RPS only supported in ARM64 devices?

It’s been available on x86 for a while now.

[rextended]

For ALL, apply this fix:

Fix for BUGS, ERRORS on default RouterOS firewall rules and firewall changes from 6.43 to 7.21.2 / 7.22beta6

[ferferga]

Just to confirm: only x86 and arm64 then, right?

[sirbryan]

Yes. You’ll see it on the Resource tab in Webfig or Winbox if it’s supported.

[dang21000]

still freez and kernel panic when disabling bpuguard

[ToTheFull]

Question re RPS, I use Fq_Codel on my WAN interface, so which interfaces do I enable RPS on.
ALL of them or just my WAN ether1 and Bridge ether2. Also whats all the fuss about with the firewall rules. Stock routerOS was 7.5

[Guscht]

no issues in smol homenet

Hi

I’ve installed it on a CRS328-24P-4S+ and all seems to work fine.

But the internal disk /files is cleaned after every reboot.

For example I make folder /firmware for capsman update packages and save the npk files.

I reboot the machine, folder and files disappeared in /files and the log also tells that update via capsman can not be done because the update files don’t exists.

Other test: making backup of config into /files, reboot the CRS328, and after reboot the file is gone.

I had 7.21.rc3 before on it, but hadn’t this problem.

Or is it a new feature??

[HoracioDos]

Hello

I've updated to V7.21.2 a few minutes ago, while updating firewall rules from @rextended post, I found that hw-offload=yes is missing now in my RB5009 in the "defconf: fasttrack" rule.

I had hw-offload=yes present in V7.20.6 because every change I do in config is under git control.

Any ideas?
Thanks!

[infabo]

"If the device has a directory named "flash" in its file list, then files which you want to be kept after the system reboot/power cycle must be stored within it. As anything outside of it is kept within a RAM disk and will be lost upon reboot. This does not include .npk upgrade files as they will be applied by the upgrade process before the system discards the RAM drive content."
Files - RouterOS - MikroTik Documentation.

[dang21000]

The same.
I found romon isn't working in defconf too.
one more release with tons of bugs...

[CGGXANNX]

That part of the 7.21 change items:

@EdPa

• firewall - hide hw-offload setting from devices that do not support it;

Only devices supporting L3HW with NAT/FastTrack will have the parameter. The RB5009 is not one of them.

CCR2xxx, CRS3xx, CRS5xx: Switch 98DX8xxx and 98DX4xxx Series - L3 Hardware...

[CGGXANNX]

Recently with the move to 7.21 there were quite a few threads on the forum (examples 1, 2, 3)where people were taken by surprise by the lack of the ability to specify the interface and VRF in tools like :ping and /tool traceroute, due to the change:

@EdPa

• winbox - Bandwidth test, Speed test, Ping, Traceroute tools use RouterOS DNS service to resolve domain names;

where the choices are expected to be manually embedded into the destination address as address@vrf%interface, with no GUI assistance in WinBox other than a plain textbox.

But it doesn't have to be like that, in fact there is another place in RouterOS that expects the syntax address%interface:

Where WinBox has good GUI support, both in WinBox 3:

and 4beta:

Could you please incorporate the same mechanism (with an additional dropdown control after @ to specify the VRF) in "Bandwidth test, Speed test, Ping, Traceroute tools"!
