Summary

I am using wireguard VPN, without any changes, my instance suddenly can't receive any udp packets

Content

I have been using wireguard to secure communications between my instances

Some of my instance located in Japan, some located in China

I have permit firewall rules on subnet and instance, my vpn has been working fine for a month.

Today, Estimated time should around GMT-8 12:15, my vpn lost connections

After troubleshooting, I found all my nodes lost connection to Oracle instance

It seems that my instance can't receive any UDP packets...

May be some security involved, Wish someone could have a look on it.

Howdy, Stranger!
