Traveling to the UAE - trying to verify real-world Tailscale behavior when routing through a personal exit node back home

Hey everyone,

​Traveling to the UAE (Dubai & Abu Dhabi) soon and trying to verify real-world Tailscale behavior when routing through a personal exit node back home.

From what I understand, UAE telecom providers (e& and du) actively block or throttle unassigned UDP and fingerprint WireGuard handshakes, and hotel guest Wi-Fi networks typically enforce strict egress firewalls that drop outbound UDP on non-standard ports.

​When Tailscale fails to establish direct UDP and falls back to a TCP DERP relay, throughput drops to near-unusable speeds.

​For anyone who has used Tailscale in Dubai/Abu Dhabi hotels - Did direct UDP work at all on hotel Wi-Fi or mobile data, or was your connection 100% forced onto a TCP DERP relay?
