I ran into an issue with this. I had done a remote fresh install of MSL 12.x but couldn't download the MBG blade because of no route to host error even after adding in routes. I had to use KMS SO5205 to fix the issue then reprogram the WAN port afterwards to get it working. We need a way to route traffic to the Mitel servers for blades and licensing out the LAN Gateway.
