We were really looking forward to using the X-series product with cloud-management. Unfortunately, we have stumpled over some rather basic issues compared to the F-series firewall.
We purchased the X-series believing it would handle split-DNS like the F-series. We use the functionality to send internet traffic to public DNS-servers and internal domain traffic to internal DNS-servers (over a VPN to our datacenter). By not supporting split-DNS, we will lose the ability to lookup DNS-queries when the VPN-tunnel goes down - preventing our users from accessing the internet.
Please consider adding split-DNS to the X-series like on the F-series. It would be much appreciated!
