Dear masters

I have one physical server in my Datacenter that installed Promox 8.2 with 2 network card
- Network card 1 with public IP: A.B.C.176 (public to internet)
- Network card 2 with local IP: 192.168.100.250/24 (gateway 192.168.100.1)
please note that the netword card 2 connect to my company network via MPLS.
The PVE host can access internet via network card 1.

In this PVE, I have one VM with IP: 192.168.100.20 and gateway: 192.168.100.1
The VM still can not access internet, it only can ping the pve 192.168.100.250, can not ping gateway 192.168.100.1

In other hand, I also have one PVE with 2 network cards in my company,
I connect the first network card to network 192.168.5.0 and the second connect to network 192.168.2.0
The VM inside this PVE is configured with IP 192.168.2.10/24 and bridge-ports eno1 (network card 2)
-> My VM still can access the internet normally.

Please give me some idea about this problem, I'm new in Promox.
Thanks a lots

ps: ah, I tried follow the guide in Promox Document, part "Masquerading (NAT) with iptables"
https://pve.proxmox.com/wiki/Network_Configuration
but nothings different.
