Re: v6.42.9 [long-term] is released!

Good point, we definitely need some option to stop bridge if all bridge ports are down (or to run it only if there are active ports). Someone just needs to contact support@mikrotik.com with that request :) I contacted support multiple times. They refused to accept that it is an issue. Oh well, Juni...

Re: v6.42.9 [long-term] is released!

So, the old master-port code is gone. Now we are stuck with bridge interfaces being always up, whether there are any ports up in the switch. I have posted repeatedly why this is unacceptable.

Please bring back security fixes for the 6.40.x releases.

Re: eBGP load balancing

Insinuating that I have not read the RFC is not particularly helpful either. The RFC tells how to select the best path which is advertised to other peers. It does not specify which routes you put into the hardware forwarding table, that is a policy decision which is outside the scope of the RFC prot...

Raw RSA IPSEC authentication

I am trying to use raw RSA authentication to interoperate with Openswan. The challenge is that Openswan keeps its public keys in a format like pubkey=0sA... whereas RouterOS apparently expects a PEM file. Is there any way to convert the Openswan format to something which RouterOS can use?

Backup with restore to different router

Is there a handy way to create a backup which will restore to a different router?

The built-in backup function in 4.6 does not get all settings transferred correctly when restored to a different router of the same model (where MAC-adresses are different).

Re: [REQUEST] Eth adapter driver | MT can't recognize adapte

Thank you very much SmalleR. I'll go for the 82576 then.

It's a bit sad if RouterOS actually uses legacy IRQ's though; that's quite a waste of a multiqueue NIC.

Re: RB600/RB800 SFP Daughtercard?

Good old PCI is 133MB/s, which would be enough for almost all our customers. You'll be CPU limited before you hit 1Gbps on the RB600 anyway.

Not that it helps us though, we'd need a 1U rack mountable cabinet for it and that's difficult with a daughterboard.

For me it's not a matter of not trusting the results. Wine isn't going on the servers in our data center. You can call that religious, but it isn't going to change. Not that a non-free-software bandwidth test application is going on them either.

If you're willing to depend on RADIUS, you could send the DHCP request off to a different DHCP-server -- possibly even running on the RADIUS-server.

Obviously this was a case where "debugging by maximising potential embarassment" was the right answer.
