    @IkkI_Magna

    For first question, Go to security policy, first rule wan to Zywall, service:NATT,IKE,ESP,AH, allow. Second rule,wan to Zywall, deny.

    For second and third question, since the Client and server are on the same subnet, please try to enable the "Allow Asymmetrical Route" on the policy control, then check it again.

    It seems DNS issue, did you ping IP address or Domain name?
    Check this example,

    Dear Jeremylin,

    After change router, some computer pop"select network location" sometimes.

    It is not always happened.

    Maybe per 1-2 months once...

    Not all computer, but some....

    If the pop"select network location" appear, it's probably connecting to different routers or connect new network.

    There is one router only.

    Client->switch-> USG110 router->internet.

    There is no other router in network.

    On my environment, I did not see this popup page during connected with USG.
    you may also tick "Treat all future networks that I connect to as public, and dont as me again" to avoid the popup page.
