Hello everybody.
I have a problem with the network configuration.
I have a Hetzner Server.
I installed ProxMox.
I added 2 virtual machines, one with Debian 11 on which IspManager is installed and another with Windows 11.
On the first machine with Debian 11 I chose vmbr0 and put the MAC of the additional IP AA.BB.CCC.EEE and there is no internet connection.
In the network configuration I have the following:
IPv4 Address: AA.BB.CCC.DDD # Main IP Address
MAC: additional IP data
Gateway: AA.BB.CCC.129
Netmask: 255.255.255.192
DNS: 213.133.98.98, 213.133.99.99 # of Hetzner
Configuration for this VM:
On the second machine with Windows 11 I chose vmbr1 and with the following network configuration:
IP address: 10.10.10.10
Subnet mask: 255.255.255.0
Gateway: AA.BB.CCC.DDD # Main IP Address
Preferred DNS server: 8.8.8.8
On this machine everything is working fine and I have access from anywhere through the main IP.
Configuration in ProxMox:
What should I do to make the first machine work? Thank you for your help.
