- Tunneling TCP connections over a TCP-based VPN leads to conflict between the reliability mechanisms of the two connections, resulting in decreased bandwidth and stutter-y performance. Always tunnel TCP over UDP when you can.
- In rare cases, overly restrictive firewalls may block UDP traffic, in which case you should obfuscate the tunnel’s UDP traffic as TCP to bypass restrictions.
- The adoption of UDP-based QUIC will make more internet traffic be on UDP, forcing firewalls to be less restrictive towards UDP traffic.
