Slow Transfer when Usign Tailscale

Hi All,

I have installed a stralink on my home and trying to setup tailscale for mt Synology ds224+ (WD SA500 4TB SSDS).

Everything seem to be working fine , i can have remote access to dsm , SMB, AFP but the transfer rate when i uploading a file to the file server is annoying slow.(10 mins for 20 mb) i followed the steps that tailscale suggests but still. Anyone can give me a hand on this ?

I only use it for File sharing and calendar ,

any help will be appreciated !!
