Extremely Slow SMB Transfer Speeds When Connecting Through Tailscale VPN on OpenMediaVault/Proxmox Setup

Hello everyone,

I'm running OMV (OpenMediaVault) on top of Proxmox VE on my machine, and I'm running the VPN (Tailscale) within OMV to enable SMB connections from outside my network.

However, when I connect to SMB over the VPN, the transfer speed becomes extremely slow as shown in the image.

Could you please advise me on how to fix this issue?

By the way, when I connect locally without going through anything, I get around 150Mbps.

Someone please help me
