Hi folks, there are some rumors on Google that IPsec connections to Apple devices are distorted, if the IP provider is Unitymedia. Some say, Unitymedia sets the ECN bits on the IP traffic without looking, and the IPsec implemen- tation on MacOS/Ios is supposed to drop these packages, according to
https://tools.ietf.org/html/rfc3168#section-9.1.1 (if I got this correctly). Can anybody confirm or deny? I don't have Unitymedia at home, but several colleagues complain that they cannot establish a stable connection to our Strongswan gateway in the office. All use Unitymedia. Every helpful comment is highly appreciated Harri
