One mobile operator in central europe allows ICMP on all phones...
- slirpee 11y agoI was tinkering with DNS tunneling for free mobile internet, and found that TCP port 53 was apparently unfettered. (Other traffic I tried was firewalled, and HTTP was captured and redirected to a page prompting to buy a data plan.) I guess the intention was for DNS over TCP, but I was able to ssh over that port and got decent speeds and no apparent tampering of the traffic.
