route the ip address after authentication



  • my portal is fully functional, but i just want to add an features to configure on changing the ipaddress after they enter the valid voucher code or an username and password,

    Examples; they connected to 10.10.10.1-100 > this is the captive portal page and they get an ip address 10.10.10.1-100 and then afther the authentication the ipaddress will get change to 192.168.20.1-255.



  • @netx34 said in route the ip address after authentication:

    then afther the authentication the ipaddress will get change to 192.168.20.1-255.

    This can't happen - not on the network called Internet (Ethernet) as we know it.
    It's the client-device that declares his IP (== static, not a good choice when using unknown , like captive portal networks) or DHCP : it asks an upstream DHCP server for network info.
    Forcing a client device to change IP settings on the fly : never saw that before.

    What you want needs a smart switch or even router in between with VLAN capabilities, routing rules, and the captive portal to set some VLAN after logging in. I guess with FreeRadius and again, some intermediate hardware, it can be done.
