Hello,
We have a few MT 411A deployed at a private client site, behind a firewall/proxy server that requires authentication. Therefore, we have no direct Internet access without supplying credentials. From what I can see, the only way to update to the new license version is by pushing the "update license key" option in Winbox.
Is there a way to supply proxy credentials, or alternately, a method to manually update the license key? We're currently in the 72 hour Window of Doom as I write this.
Thanks!

The RouterOS device itself does not need Internet access, only the machine running Winbox does (as it fetches the license from the machine running Winbox, and then deploys it to the RouterOS device). So authenticate your laptop/desktop/whatever and you should be fine. Worst case, get a 3G card or a dial up modem or any other method of OOB connectivity for the machine running Winbox.

Well, it still doesn't quite work through this proxy, but it gave us the info we needed. We're now able to see the GET string that's being attempted, do it on another machine, then paste the results into the license.
thanks!!
