I have a performance problem with downloading files and errors when trying to git clone projects
On a Proxmox 8.2.4 server we installed a Debian12 VM that works as a firewall and then installed a Windows 11 VM following best practices and installing all the additional drivers
the windows vm is fast and also navigates internally, if you try to do a speedtest the speed is that expected from the network, but when you try to download a single file or for example download projects with git the connection is very slow, maximum 50- 60 kb/s below the VM configuration
The server provider does not apply any type of filtering on the network
How can this performance problem be resolved?
This is the configuration of VM
Code:

check storage, like crystal disk mark, with classic sequential write, like 3 x 8GB, 1 thread 1 queue,
