Hello ,

Unfortunately we cannot offer support services for other vendors products, outside of integration assistance for Genian NAC users.

I was able to find some resources from 4ipnet that should be helpful top you:

• Captive Portal config Video Demo: https://www.youtube.com/watch?v=lqfg_jCSMKU
• Official 4ipnet Technical Support: http://www.4ipnet.com/support/technical_support

We wish you well in configuring your network.

Best Regards,
Scott
