  • A lot of negativity around Ubiquity in here, which is surprising to me, honestly. I had their USG for years and loved it, recently swapped it out for the Dream Machine and love it. Really don’t understand the complaints about linking it to the cloud. I just didn’t bother, everything works fine. Additionally, I managed to get a Debian container running on it and installed ntopng, it’s been awesome for getting realtime visibility into my network traffic.

    E. I should add I have 6 of their switches and 3 access points, one of which is at least 7 years old and still receiving updates.





  • You aren’t wrong, per se, I think you just don’t fully grasp the attack vector. This is related to DHCP option 121, which allows routes to be fed to the client when issuing the ip address required for VPN connectivity. Using this option, they can send you a preferred default route as part of the DHCP response that causes the client to route traffic out of the tunnel without them knowing.

    E. It would likely only be select traffic routing out of the tunnel. I could, for example, send you routes so that all traffic destined for Chase Bank ip addresses comes back to me instead of traversing the tunnel. Much harder to detect.












  • It probably has to do with being native ipv6 and needing to ride a 6to4 nat to reach the broader internet.

    Start at 1400 and walk the MTU down by ~50 until you find stability, then id creep it back up by 10 to find the ‘perfect’ size, but that part isn’t really needed if you’re impatient. :)

    E. I found 1290 was needed for reliable VPN over an ATT nighthawk hotspot.


  • Latency plays a big role in throughput. If one download target was ‘closer’, i.e. lower latency, it will be able to scale the windowsize higher, therefore allowing more data to flow through for a given connection. Imagine network packets are envelopes and data is paper. Not all envelopes can carry the same amount of paper for a given connection, and the more paper you stuff in your envelope, the faster the transfer completes.
