Proxmox Server Networking Troubleshooting

I'm experiencing network issues inside all of my VMs on my Proxmox server. The configuration hasn't been altered recently and the VMs are set up on a bridged network. While I can access the Proxmox server's web interface and all other network services from outside the VMs, the internal networking within the VMs is not functioning as it should.

I need an expert to diagnose and fix this issue, preferably using Anydesk, as soon as possible.

Ideal Skills:
- Deep understanding of Proxmox server
- Strong networking troubleshooting skills
- Ability to work under pressure
- Experience with bridged network setups
- Proficient in remote desktop troubleshooting (Anydesk)
