Remote home server access slow over VPN

VPN
1

My home setup is as follows:

UDM-SE on a FIOS gigabit connection.
Synology 918+ NAS with shared folders for movies, tv, etc…
PiVPN on a pi4b.
Wireguard on a remote Shield TV Pro (2019).
Folders mounted in Kodi using NFS.
Accessing the home network over a FIOS 300/300 connection.

The video playback using Kodi, when accessing my home network over the VPN, stutters and freezes with frequent “connection too slow for continuos playback” errors. I don’t have any issues accessing content on my home server using Plex (verified plex was streaming through the VPN via the Plex dashboard). Also content plays fine using kodi on a Shield Pro located in my house. Any suggestions to fix the issue? I prefer the Kodi interface with Aeon Nox Silvo over Plex.

Depends how the Kodi source is setup. Your Kodi doesn’t know about all your setups, analyse and post Kodi log

Configure the vpn setup on the synology, and allow other computers on your network to access vpn using synology (it’s a checkbox on the vpn config on the synology)

You can then also set up a proxy server (with or without cache) on the synology. That’ll solve all your file access routing - it sounds like right now your file access is routed via your vpn connection (Shield → von gateway → vpn endpoint → back to your vpn client machine → synology nfs)

Also maybe use NFS via direct IP TO access your files on the synology

Would like to keep my existing VPN setup if possible. I have used it for a couple of years now without issue.

The only app I’m having an issue with is Kodi on the remote Shield, mostly with high bandwidth 4k H265 files. The same files play flawlessly using Plex or VLC on the remote shield. I can also transfer multi-gig files through the VPN and max out the remote FIOS connection. Makes me wonder if I have something configured wrong in Kodi. Although the same files play fine on a locally connected shield.

Do not expose your Synology direct to the internet, ever. basic security, do not expose your NAS or any storage device direct to the internet, period! You will get compromised sooner rather than later when the next Synology or QNAP or what ever exploit comes around.

Can your PiVPN handle 300? and the PiVPN is it actually wireguard? or is it VPN?
