Description

Captive Portal on Lightweight Controller (LWC) currently allows you to configure static IP addresses for connecting to AWS, and to internal devices.  However, it does not allow you to configure IP address via DHCP.  This article provides a workaround until configuring IP via DHCP is supported.

Symptoms

Cannot configure DHCP on Captive Portal

Solution

The workaround requires a deviation from the official documentation (LWC Platform Hardware Guide - Configure the Network Ports and Active Proxy).  Specifically step 3 in the documentation, do not connect using  https://cportal.lwc.jssdev.junipercloud.net; instead use the following instructions.

Key points: 
  • Must manually assign an address to the connecting device
  • Must accept an unsecure connection
Workaround: Connecting The Laptop
  1. Manually assign the following configuration to the interface connected to the LWC 
    IP:  10.85.198.144
NETMASK:  255.255.255.224
GATEWAY:  10.85.198.129
  2. Enter the following connection 
    https://10.85.198.145
  3. Use the browsers advanced settings to accept the connection

    Once connected, follow the remaining instructions in LWC Platform Hardware Guide - Configure the Network Ports and Active Proxy (step 4) to configure the LWC.
