VM and LXC has no internet connection but PVE Host has

[darkdiablo]

Hello, I'm currently facing a problem that VM and LXC cannot connect to the Internet.
Background:
The PVE node and my PC is inside the isolated network (on the right)
PVE Host can apt update normally, but ping google.com doesn't work (probably because company has blocked it)



So far, I've tried:

1. Set Proxy server for the VM (using company proxy server)
2. Set DNS (following company internal DNS)
3. I can ping from this VM to my PC and PVE host
