Use Separate WireGuard Interfaces or Profiles

Use Separate 스포츠중계 WireGuard Interfaces or Profiles

If you're using your PiVPN for multiple tasks (e.g., Plex + SSH + web access), you can:

Create multiple WireGuard profiles with different purposes
Example:
- plex-only.conf: Routes only Plex-related IPs and ports
- full-tunnel.conf: Routes all traffic through VPN

In your plex-only.conf:

ini

복사편집

AllowedIPs = 192.168.1.50/32

This will only route traffic to your Plex server (e.g., 192.168.1.50), leaving all other traffic outside the tunnel for speed.

???? Benefit: Reduces load on your VPN and gives Plex the full pipeline.

✅ 2. Enable Quality of Service (QoS) on Your Router

Most modern routers offer QoS settings that let you prioritize traffic based on:

Port number
IP address
Device (MAC address)

Example:

Plex typically uses port 32400
Your Plex server might be at 192.168.1.50
In your router QoS settings:
- Set high priority for:
  - Outbound traffic on port 32400
  - Device IP: 192.168.1.50
  - Service: WireGuard (UDP port 51820)

This ensures your router allocates top-tier bandwidth to Plex sessions, even if others are uploading or gaming.

✅ 3. Use Policy-Based Routing or Split Tunneling

If your VPN server is running on a Linux machine or router, use iptables or ip rule to:

Route Plex-bound traffic (e.g., Plex clients or Plex IP) through a dedicated interface
Deprioritize other VPN routes or leave them out of the tunnel

Example:

bash

복사편집

ip rule add from 192.168.1.100/32 table 200 ip route add default via 10.6.0.1 dev wg0 table 200

This will route only traffic from your Plex client (e.g., your mobile device abroad) through the VPN

✅ 4. Optimize 스포츠중계 MTU for Plex Traffic

MTU (Maximum Transmission Unit) mismatch causes latency spikes and buffering.

On WireGuard config:
```
 
```
ini

MTU = 1420
You can experiment with 1400–1420 to see what performs best for your connection

Test using: ping -M do -s 1472 [your home IP] and subtract 28 bytes.

✅ 5. Monitor Real-Time Traffic and Logs

Use tools like:

iftop / nload / vnstat on the VPN server
Plex Dashboard to confirm Direct Play or Transcoding
htop or btop to check CPU load and bandwidth usage

See if Plex traffic spikes are being affected by other processes like SSH, FTP, or backups.

???? Bonus Strategy: Run PiVPN and Plex on Separate Devices

Host PiVPN on a Raspberry Pi or router
Run Plex on a separate PC or NAS
This isolates load and avoids port conflicts or resource hogging

???? Recap: Ways to Prioritize Plex Over VPN

Method	Priority Boost?	Complexity
Split VPN profile (AllowedIPs)	✅✅✅	Easy
Router QoS	✅✅	Moderate
iptables / policy routing	✅✅✅	Advanced
Dedicated devices	✅✅	Moderate
MTU tuning	✅	Easy
