    Hi,

    I'm trying to set up a splash screen for my wired clients if they are put in a untusted vlan due to profiling confilicts or unknown Mac.

     

    - Switch is HP 5406 with Firmware 16.08.001

     

    show port-access clients B7 detailed  shows me the corret VLAN, Correct ACL and the correct captive portal string

    ...

    Untagged VLAN : 666

    ...

    RADIUS ACL List :
    permit in tcp from any to 10.1.1.46 80
    permit in tcp from any to 10.1.1.46 443
    deny in tcp from any to any 80
    deny in tcp from any to any 443
    permit in udp from any to any 53
    permit in udp from any to any 67

    ...

    Captive Portal Details :
    URL : http://10.1.1.46/mysite.htm

     

    show captive-portal

    Captive Portal Configuration

    Redirection Enabled : Yes
    URL Hash Key Configured : No

     

    - The captive portal is in VLAN1 - also the switch Mangement

    - the Switch has a static IP in VLAN666

    - for the clients I created a firewall rule so that they ca reach the ip of the captive portal

    - the client can reach the page if i open it directly in the browser

     

    But there is no redirect happening if i try to open any other site in the explorer. Tested with Win10 - Edge, Firefox, InternetExplorer - local Firewall disabled.

     

    Any Ideas

    Does the client have a valid and working (nslookup resolves...) DNS server?

    Usually yes, since the controller/switch will intercept the initial DNS
    reply and re-direct this to the Captive Portal. Without a working DNS
    server, there is no DNS reply and therefore no re-direct occurs.
