After the configuration is synchronized, the actual VM flow appears. Workaround: Modify the time window to exclude the flow you do want to see.

For further assistance with this issue, please contact Microsoft Support. Security profiles can be used by more than one security policy. You can configure sets of security profiles for the traffic types handled by a set of security policies that require identical protection levels and types, rather than repeatedly configuring those same security profile settings for each individual security policy. I tried the "set flow tcp-mss" without luck. I also have these items set: set flow tcp-mss set flow all-tcp-mss 1350 set flow path-mtu set flow max-frag-pkt-size 1250 unset flow tcp-syn-check-in-tunnel With all of the above set, it is still taking about a minute to receive the welcome screen even though the session has been opened.
