I think that the value of this article is perfectly summarized by the sentence “Not sure what SYN is.”

are you saying that a packet leaving iOS and hitting the router's logs, without going through the "VPN" does not leak either your IP to the destination or your destination to your ISP?

  I think he’s saying that any sort of network analysis done by someone that doesn’t understand basics of TCP is kinda suspect and may be more prone to errors in the analysis methodology or interpretation of results. I tend to agree. My only takeaway after seeing that was “if I ever need a 100% leak free tunnel on iOS, validate it”. I certainly won’t be taking any of this at face value without replicating it.

    the local router shouldn't see any other connections inbound or outbound from the device other than the "VPN" ip you are connected to. I submit that it doesn't take an expert to come to that conclusion. Other comments in this thread explain that the iOS/MacOS kernel keep old established routing tables intact under some circumstances, and that's (one) issue. Another appears to be the unreliability or inconsistency of "airplane mode" and invalid assumptions about that.

      > I submit that it doesn't take an expert to come to that conclusion. Probably not, but if, in the middle of trying to diagnose my car, someone pointed to the muffler and said "I'm not sure what this thing's for." I probably would look for a second opinion on their diagnosis especially if it was "there is a major manufacturing defect in this model of automobile". It doesn't matter if the problem looked like it was staring us in the face. Obviously I can't spot any major flaws with what the writer put together after a single read or I'd be pointing them out. I'm not calling it wrong. I'm just saying I'd want more verification from someone that has a better understanding of networking concepts to make it less likely that basic mistakes impacted the outcome. If the write-up has given you enough confidence, all the power to you.

    Typically, but it does not summarize this content. The author repeatedly says he doesn’t know much about most of all the things but he also knows he can test things out by just watching the activity in his router logs. And, it’s not good.
