Ah! Interesting. I'll look into an ARP proxy. And report back.

I needed a solution sooner, so I just installed another OPNSense instance on that site; which worked well. I wasn't looking forward to managing another eight server/appliances, but at the end of the day it's whatever works!

General Discussion / Captive portal with multiple routed networks

« on: January 12, 2017, 07:22:20 pm »

Hello everyone! I was originally looking for a simple captive portal - no auth, no DHCP, nothing fancy just a splash page with instructions on how to connect to our networks BYOD guest Wifi. OPNSense was the first solution I found that just worked out of the box.

That is it's working well on the network attached to an interface. I'm struggling to get a routed network to work through it, however. I've spent a couple of days troubleshooting and searching these forums (and of the original project's forums, google etc.)

Here's what I know:
Routed clients can access the OPNSense IP address, browse, get to the Captive Portal splash page and even "Agree"  - creating a session. After this, requests just time out. DNS is working - names are resolved. I don't see any blocked traffic from a sample client in the Firewall logs.

Likely the environment is too complicated to get a simple answer, but I would like some help diagnosing. Where can I look to see where this traffic is failing? Is there somewhere I can see the operation of the Captive Portal? Firewall? I have looked at the links from the web GUI, but they don't seem to show anything of interest.
