Captured Packets on Flex H shows double packets on some packets on the receive and a ping down a tunnel is shown in the capturer that shouldn't be seem and USG60W 192.168.254.9 did not send it out of the tunnel just that the Flex H Packet Captured shows it as out of the tunnel when its not.

    Hi @PeterUK

    Regarding the duplicate packets, this is a known issue stated in the USG FLEX200H V1.21(ABWV.0) release note, “[ZNGA-3386][eITS#230701453] Duplicate packets in captured packet file.”

    Additionally, the tunnel traffic display issue, where capturing on the WAN side may show VPN tunnel packets, is also known. This is only a display issue; your ping is still correctly encapsulated within the VPN tunnel. We will update the release notes later.

    Both issues are planned to be fixed in the future.
