IPV6-only environment gets stuck on "IPXE initialising devices".

[ghost]

I'm currently trying to get netbootxyz to work in a IPV6-only environment. I'm using the Ansible role to deploy netbootxyz and serve the TFTP server for PXE clients using network booting from OPNsense.

So far i've managed to get both the .kpxe & .efi images to sucessfully boot and install CD's using IPV4 internally. With IPV6 I simply have not have not gotten any further than "ipxe initialising devices". Using the snp & snponly.efi images i've atleast seen "netboot.xyz" post, until it fails booting from HTTP.

Has anyone got some advice on how to get netbootxyz up and running using only IPV6?
