In SGOS 22.214.171.124, the ADN Core SG8100 sends DUP ACK to an edge ProxySG on ADN tunnel ports 3035 and 3037.
An SG8100 running SGOS versions 126.96.36.199 to 188.8.131.52 and serving as an ADN Core sends duplicate ACK message to the edge ProxySG on ADN tunnel ports 3035 and 3037. This behavior is not seen in Managed ADN deployments on port 3034 and 3036; it is also not an issue in SGOS 184.108.40.206.
This problem can be found in certain TCP network settings, ADN or SSL proxy implementation.
This issue was fixed in 220.127.116.11 or later, 18.104.22.168 or later.
