We're running 220.127.116.11.16189.RELEASE and it's working brilliantly. However, we're coming up to the 30-day callback threshold and we're not convinced the device is getting back to the ALSI* addresses.
We can ping internet FQDNs and IP addresses from the appliance without errors, but when we go to System Configuration > System Administration > Update licence it reports it cannot/isn't connected to the internet.
Our key issue is that we can't see how to force a licence callback and/or check when/if it has attempted the daily callback, nor are we clear on warnings about approaching the 30d limit. We estimate we're going to hit 30d on Sunday 3rd May 2018
We're 99% satisfied there is a route out to the web, Firewall is correctly configured, packet traces look OK, VM MAC is static,
We can re-create the Kemp from scratch if required.
