Many years ago, when hotels first started having and charging for WiFi connections, I wrote a simple little tunnel using the DNS port back to my server. Since the hotels didn't block that port or even bother to check what traffic was going over it, it worked like a charm.
I tried it on a trip to Tokyo and immediately got completely blocked. It took me a few minutes to figure out they'd blacklisted my MAC address. I changed the MAC of that interface and then behaved.
- someotherperson 3y agoReminds me of using VPNs in hotels in China some years ago. Traffic would work for a few minutes and then the Great Firewall kicks in, fingerprints the traffic as VPN and the IP address and the MAC gets blocked. I'd rotate the endpoint and the MAC address and get a few more minutes, rinse and repeat. I think I had to use Shadowsocks or something at the end to completely bypass it.
