Thu Aug 10, 2017 12:35 am

Hello again. Brand new RB3011 with RoS 6.40.1. For l2tp+ipsec I want to import two certificates, one for remote server and one for mikrotik itself. But something going wrong.
this is my certs and keys
admin@MikroTik] /file> print

Then go to certificate:

[admin@MikroTik] /certificate> 
There is nothing. Now import first cert and key

Nothing is strange.
Then import the second cert

[admin@MikroTik] /certificate> 
There is something strange. I have to see two certificates, but there is one, and it is a little bit weird. It has the name from cert1, common-name from cert2. Why is there one certificate? Do i do something wrong?

Re: can't import 2 cert and key

Guys, trouble in RoS 6.40.1. I downgraded to 6.38.7 - imported all certificates without any problems. Bug presents in ARM and MIPSBE(other platforms i didn't check). It, maybe, will help someone.

Re: can't import 2 cert and key

I am also seeing this behavior on my ROS 6.40.3 and 6.40.1. I wonder if this issue is because the issuer is the same self signed ca. the Cert name, CommonName, and Subject Alt names are different but when I import the second cert it always replaces the first cert imported with the second one. I have tried it from cli and winbox no difference.

So I import flash/NjVpnHubCert.pem
[admin@MikroTik] > certificate print

Notice how the Name part stays the same but the Common-Name and Subject-Alt_Name change as does the fingerprint.

Then I delete NjVpnHubCert.pem and then import flash/OfficeNetCert.pem I get

When I import them one at a time and view their details they are good. I can import either one first and the second one will always overwrite the first one whichever I do first and second.

I am running this on a CRS326-24G-2S+. Is this support ticket area we are into now? Anyone else having an issue like this except the two of us?

Thanks.

Same problem. One certificate overwrites the other and vice versa.
