Good day.
I'm from Russia.
I am writing with the help of Google translator.

The third day I'm trying to figure out Proxmox VE 6.2

Managed to forward the GPU through the GPU passthrough.

And happiness was very close, but.

After all attempts to start the network on the guest machine, I failed.

Knowledge on setting up networks. I also have almost no knowledge of Linux

In my home network, I have a simple dlink dir-615. Pinged at 192.168.0.1

Motherboard z490 aorus master

file /etc/network/interfaces
Code:
auto lo
iface lo inet loopback

auto enp5s0
iface enp5s0 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.0.48/24
        gateway 192.168.0.1
        bridge-ports enp5s0
        bridge-stp off
        bridge-fd 0


List of connections in the router
Code:

XX:XX:XX:XX:XX:XX    192.168.0.20    rockrobo    reachable    WLAN

Proxmox web interface address https://192.168.0.48:8006/

vmbr0 received the ip address 192.168.0.23 (I look at the connection status) gateway 192.168.0.1

tried e1000 and virtIO

Is there any obvious solution to the problem? Maybe in a new connection I need to specify a different IP?
From the guest machine, the address 192.168.0.48 responds well. No more addresses are visible. There is no internet either.

Can I do something at my low level of understanding? In general, it seems to me that I have a good understanding of the basic basics of settings and interaction with the hypervisor itself.

Thanks for any help :)

Code:
auto lo
iface lo inet loopback

auto enp5s0
iface enp5s0 inet static
        address 192.168.0.48
        netmask 255.255.255.0
        gateway 192.168.0.1
        up route add -net 192.168.0.48 netmask 255.255.255.0 gw 192.168.0.1 dev enp5s0


auto vmbr0
iface vmbr0 inet static
        address 192.168.1.1
        netmask 255.255.255.0
        bridge-ports none
        bridge-stp off
        bridge-fd 0

        post-up echo 1 > /proc/sys/net/ipv4/ip_forward

        post-up iptables -t nat -A POSTROUTING -s '192.168.1.0/24' -o enp5s0 -j MASQUERADE
        post-down iptables -t nat -D POSTROUTING -s '192.168.1.0/24' -o enp5s0 -j MASQUERADE
