Symptom:
You are unable to establish Nebula Site to Site VPN But using the non-nebula method is no problem.
You find there were Fragmented packets when IKE negoiated.
Workaround:
This is because Nebula VPN establishes connections using certificates, which can cause issues with ISPs that have smaller MTUs.
Please use a non-Nebula VPN as an alternative.
