Sophos XG has no Internet in Discover Mode

Hi everyone,

Here's my Sophos XG setup:

Deployment: Hyper-V 

Mode: Discover (https://community.sophos.com/kb/en-us/122971)

vCPU: 4

RAM: 6GB

Storage: 100GB

vNICs: Two

  1. First NIC: Management interface/LAN
  2. Second NIC: Discover

However, the device has no Internet access. I have the right DNS server setting (I tested it). The First NIC is on a static IP. Do i need to change the First NIC to WAN in order to get Internet access?

Please advise.
