    Took me some time to work this out and the fix is there needs to be a routeing rule next hope to remote VPN.

    The problem is this if you have a routing like
    incoming LAN
    next hop WAN
    SNAT outgoing-interface

    When VPN traffic goes to LAN it gets to the device then a reply happen but the traffic to the VPN IP follows the routeing rule above and so never get back to the client.

    There is no routing rule you can make to fix this but there is a workaround
    make two address objects with the following range if your VPN IP pool is 192.168.50.0/24
    0.0.0.0 - 192.168.49.255
    192.168.51.0 – 255.255.255.55
    in a group
    Then add that to the above routeing rule for Destination Address
