Unable to connect to Internet on OrangePi 5 Plus (Host)

[cclngit]

Hello, my main board is currently unable to connect to the internet. The OrangePi 5 Plus features two Ethernet ports, and I aim to designate them for WAN and LAN. To achieve this, I've created two bridges: vmbr0 for WAN (enP3p49s0) and vmbr1 for LAN (enP4p65s0), intending to implement a firewall. Currently, only VMs directly attached to vmbr0 can access the internet. However, as I am not proficient in configuring /etc/network/interfaces, I'm uncertain if there's an issue with my configuration. Could you please review it?

The configuration is fine, it may require you to check your network topology

[cclngit]

Yes, it's my network topology, I managed to get it work. The probleme came from the gateway, it's 192.168.1.254 instead of 192.168.1.1.
